Why does a balloon filled with gas become smaller when placed in a colder environment?
A.atoms / molecules speed up in the cold and thus push out on the balloon more
B.atoms / molecules slow down at lower temperatures and thus push out on the balloon less frequently and with less energy
C.atoms / molecules slow down in the cold and thus push out on the balloon more
D.atoms / molecules speed up in the cold and thus push out on the balloon less

Answers
Answer:
B
Explanation:
If you remeber a balloon in hot air, it pops. This is because the molecules are moving too fast and need more space to move, thus popping the balloon. If you put a balloon in cold air, then it shrinks, the molecules not moving fast enough and don't need as much space.

Rosalind Elsie Franklin (25 July 1920 – 16 April 1958)was a British biophysicist and X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal and graphite. The DNA work achieved the most fame because DNA (deoxyribonucleic acid) plays essential roles in cell metabolism and genetics, and the discovery of its structure helped scientists understand how genetic information is passed from parents to children.
rosalindfranklin
Franklin is best known for her work on the X-ray diffraction images of DNA which led to discovery of DNA double helix. Her data, according to Francis Crick, was "the data we actually used" to formulate Crick and Watson's 1953 hypothesis regarding the structure of DNA.Franklin's X-ray diffraction image confirming the helical structure of DNA were shown to Watson without her approval or knowledge. Though this image and her accurate interpretation of the data provided valuable insight into the DNA structure, Franklin's scientific contributions to the discovery of the double helix are often overlooked. Unpublished drafts of her papers (written just as she was arranging to leave King's College London) show that she had independently determined the overall B-form of the DNA helix and the location of the phosphate groups on the outside of the structure. However, her work was published third, in the series of three DNA Nature articles, led by the paper of Watson and Crick which only hinted at her contribution to their hypothesis.
After finishing her portion of the DNA work, Franklin led pioneering work on the tobacco mosaic and polio viruses. She died in 1958 at the age of 37 from complications arising from ovarian cancer.

Question: Explain how each of the three types of energy transfer occurs in a solar oven while it cooks a bowl of soup.
Read below for some ideas of the answer and if you answer please make your answer reasonable.
To remove a metal pan from a hot oven, you must use an insulated pad or glove. If you do not, energy will transfer quickly to your hand by conduction. The pan is much hotter than your skin, so its particles have a lot more thermal energy. When the particles of the metal bump into the particles of your skin, energy is transferred.
When the hot pan is on top of the stove, you can tell that it is hot by holding your hand above the pan. The moving air around the pan absorbs energy and carries it to your skin by convection. You can also absorb energy by holding your hand to the side of a stove’s heating element. Energy is transferred through radiation to your skin.
Energy in the form of heat can be transferred by conduction, convection, and radiation. During all three types of energy transfer, the thermal energy of the warmer object decreases and the thermal energy of the cooler object increases. In all three types of energy transfer, energy is being transferred to a cooler object.

Converting light energy to heat energy: Solar cookers concentrate sunlight onto a receiver such as a cooking pan. The interaction between the light energy and the receiver material converts light to heat and this is called conduction. This conversion is maximized by using materials that conduct and retain heat.
Explanation:
Solar cookers focus sunlight onto a recipient, like a cooking pan, to convert light energy into thermal energy.
What is energy?Energy is the ability to perform work in physics. It could exist in several different forms, such as potential, kinetic, electrical, chemical, thermal, electrical, radioactive, etc. Additionally, there is heat and work, which is energy being transferred from one body towards another. Energy is always assigned based on its nature once it has been transmitted.
Motion is a property of all energy types. For instance, if a body is moving, it possesses kinetic energy. Even while at rest, a tensioned object like a spring or bow has the ability to move; this is because of its design, which includes potential energy. Solar cookers focus sunlight onto a recipient, like a cooking pan, to convert light energy into thermal energy. Conduction is the process by which light energy is transformed into heat by interacting with the receiver material. Utilising heat-conducting and heat-retaining materials will maximise this conversion.
Therefore, Solar cookers focus sunlight onto a recipient, like a cooking pan, to convert light energy into thermal energy.

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answers
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.
Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

The area where the land meets the sea is called the coastline. This area can have different physical features depending on its location. Some common features of coastlines are beaches, cliffs, bays, harbors, estuaries, and dunes. Beaches are made up of loose particles like sand and gravel that are deposited by the sea.
In some areas, the shoreline may consist of a wide, sandy beach, while in others it may be rocky and steep.
In general, the shoreline is where the land transitions to the sea, and it is often marked by the presence of waves, tides, and other oceanic phenomena.

Use this formula: KE=0.5mv²
Kinetic Energy (KE) is measured in Joules (J)
Mass (m) is measured in kilograms (kg)
Velocity (v) is measured in meters per second (m/s)
A) KE = 0.5 x 28 x (2)2 = 556 J
B) KE = 0.5 x 2 x 28 x 2 = 56 J
C) KE = 0.5 x 2 x (28)2 = 784 J
D) KE = 28 x 2 x (0.5)2 = 14 J
Answers
Answer:
The correct answer is C) KE = 0.5 x 2 x (28)2 = 784 J.
This is because the kinetic energy of an object is equal to one half times the mass multiplied by velocity squared.
In this case, the mass of the ball is 2 kg and the velocity is 28 m/s, so the equation would be KE = 0.5 x 2 x (28)2 = 784 J.
Answer:
KE = 784 J

a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Dew point is the temperature at which water vapor in the air begins to condense into liquid water. The higher the dew point, the more moisture there is in the air. From the starting sounding in the simulation, change the temperature for each point between 800 hPa and 1,000 hPa to 40°C. Then, test how changing the two dew points closest to Earth’s surface (while keeping the temperature constant) affects whether a cloud forms and how big the cloud is if it does form. Describe what you observe, and explain why it occurs.
Answers
Answer:
Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure.
When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation. This process results in the formation of tiny water droplets that can lead to the development of fog, frost, clouds, or even precipitation.
Relative Humidity can be inferred from dew point values. When air temperature and dew point temperatures are very close, the air has a high relative humidity. The opposite is true when there is a large difference between air and dew point temperatures, which indicates air with lower relaitve humidity. Locations with high relative humidities indicate that the air is nearly saturated with moisture; clouds and precipitation are therefore quite possible. Weather conditions at locations with high dew point temperatures (65 or greater) are likely to be uncomfortably humid.

Locations with high relative humidities indicate that the air is nearly saturated with moisture; clouds and precipitation are therefore quite possible. Weather conditions at locations with high dew point temperatures (65 or greater) are likely to be uncomfortably humid.
As per the given scenario, the temperature for each point between 800 hPa and 1,000 hPa is changed to 40°C. This means that the temperature of the air at all those altitudes is the same.
What are dew points?Dew point is the temperature at which the air becomes saturated with water vapor, leading to the formation of dew, fog, or clouds when the temperature drops further.
Now, the two dew points closest to Earth’s surface are changed while keeping the temperature constant. Dew point is the temperature at which water vapor begins to condense into liquid water. Therefore, changing the dew point changes the amount of moisture in the air.
When the dew point is close to the air temperature, the relative humidity is high, and the air is almost saturated with water vapor. In such a case, if the dew point is raised even slightly, the air becomes saturated, and the water vapor condenses into liquid water.
On the other hand, if the dew point is lowered, the relative humidity decreases, and the air becomes drier. In such a case, the chances of cloud formation are reduced.
Therefore, if the dew point is raised close to the air temperature, a cloud forms. The size of the cloud will depend on the amount of moisture present in the air. The higher the dew point, the more moisture there is in the air, and the bigger the cloud will be.
