Lina and Vera purchased fruit pops at the grocery store. The drive home was hot, and the fruit pops turned slushy. Increased temperature means particles have greater motion.

What is temperature ?

Temperature is a physical quantity that quantifies our feelings of hotness and coldness. A thermometer is used to measure temperature. Thermometers are calibrated in a variety of temperature scales that have historically been defined by various reference points and thermometric substances.

Temperature is a measure of a system's average kinetic energy. As particles in a matter move faster, their kinetic energy increases, raising the temperature of the system. Heat is defined as the energy exchanged when two bodies of different temperatures come into contact.

The total energy of all molecular motion inside an object is defined as its heat. Temperature is a unit of measurement for the thermal energy or average heat of molecules in a fluid.

Thus, option A is correct.

What is an ellipse please help)

Answers

normal oval shape traced by a point moving in a plane so that the sum of the distance from the other points is constant.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

(B) a gentle wind

(C) low humidity

(D)a thunderstorms

Answers

Answer:

the answer is D) A Thunderstorm

Explanation:

when warm air and cold air interlope in the sky/clouds they create uneven air quality and a thunderstorm happens

When cold air and warm air meet the air quality becomes uneven therefore a thunderstorm commences

What is true for two pieces of iron at the same temperature that are different mass?

A) The average kinetic energy of their particles is different.
B) Heat flows from the larger object to the smaller object.
C) The total thermal energy of their particles is different.
D) Heat flows from the smaller object to the larger object.

Answers

Answer:

Their particles have the same total kinetic energy.

Explanation:

Their particles have the same total kinetic energy.

C) The total thermal energy of the particles in each piece of iron will be different, because the total energy of a substance is proportional to its mass. However, if they are at the same temperature, their average thermal energy per particle will be the same.

What is one way these stems help these cactus plants survive?

A. They take energy from sunlight.
B. They take minerals from soil.
C. They hold the plant in the ground.
D. They make seeds for reproduction.

Answers

Answer:

Explanation:

A cactus stores water in its stem, which allows it to survive and thrive in desert-like environments. Its stem is made up of thick, spongy tissue that helps to absorb and retain large amounts of water. This stored water is then used to keep the cactus hydrated during times of drought and heat.

B.They take minerals from soil

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s
