A scuba tank contains air at 2975 psi and 25°C. The tank is left in a car in the
hot sun and the temperature increases to 44°C. What will be the pressure (psi)
in the tank?
Answers
Answer:
The new pressure is 3164.58 psi.
Explanation:
We have,
Initial pressure, \(P_1= 2975\ psi\)
Initial temperature, \(T_1=25^{\circ}=298.15\ K\)
The tank is left in a car in the hot sun and the temperature increases to 44°C, \(T_2=44^{\circ} =317.15\ K\)
Let \(P_2\) is the final pressure in the tank. Gay Lussac's law,
\(P\propto T\\\\\dfrac{P_1}{P_2}=\dfrac{T_1}{T_2}\\\\P_2=\dfrac{P_1T_2}{T_1}\)
Plugging all the values,
\(P_2=\dfrac{2975\times 317.15}{298.15}\\\\P_2=3164.58\ psi\)
So, the new pressure is 3164.58 psi.

A = Smooth Endoplasmic Reticulum
B = Vacuole
C = Mitochondria (Plural)
D = Nucleolus
E = Cell Wall
Explanation:
This is obviously a plant cell. Animal cells do not have cell walls(E), and most animal cells will not have a vacuole(B). Smooth Endoplasmic Reticulum: This produces protiens (contains ribosomes) but when looked through a microscope, will appear to be smooth. The vacuole(B) is like a storage for the plant cell, and it helps support the plant cell. This is the reason why plants “droop” when you don’t water them for a long time. Mitochondia (Plural) processes nutrients for the cell. The nucleolus(D) covers the nucleus. It’s main function is to process RNA and combine it with proteins. The cell wall(E) helps support and protect the cell.

Given: 8CO + 17H2 → C8H18 + 8H2O In this chemical reaction, how many grams of H2 will react completely with 6.50 moles of CO? _______ grams of H2 will react completely
Answers
Answer:
27.63 g of H2.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
8CO + 17H2 → C8H18 + 8H2O
Thus, we can say that:
From the balanced equation above,
8 moles of CO reacted with 17 moles of H2.
Next, we shall determine the number of mole H2 that will react completely with 6.50 moles of CO.
This can be obtained as illustrated below:
From the balanced equation above,
8 moles of CO reacted with 17 moles of H2.
Therefore, 6.5 moles of CO will react with = (6.5 x 17)/8 = 13.813 moles of H2.
Therefore, 13.813 moles of H2 is needed to react completely with 6.50 moles of CO.
Finally, we shall convert 13.813 moles of H2 to grams. This can be achieved by doing the following:
Molar mass of H2 = 2x1 = 2 g/mol
Mole of H2 = 13.813 moles
Mass of H2 =.?
Mole = mass /molar mass
13.813 = mass of H2 /2
Cross multiply
Mass of H2 = 13.813 x 2
Mass of H2 = 27.63 g
Therefore, 27.63 g of H2 is needed for the reaction.
Which of these statements best describes which traits are expressed by an organism? A. An organism expresses all the traits for which it carries genes.
B. An organism expresses only the traits whose genes are inherited from a parent.
C. An organism expresses only the traits whose genes it will pass on to its offspring.
D. An organism expresses some traits for which it carries genes while others are dominant
Answers
The statement that best describes which traits are expressed by an organism is A.
An organism expresses all the traits for which it carries genes. This is because an organism's traits are determined by the combination of genes it carries, which includes both dominant and recessive genes. Even if a trait is not expressed in an organism, it can still be carried in its genes and passed on to its offspring. Therefore, all the traits for which an organism carries genes have the potential to be expressed in either the organism or its offspring.
B-An organism expresses only the traits whose genes are inherited from a parent.

D. it can travel high to low and low to high
Answers
Answer:
b. high to low.
heat dissipates, spreads out.
The transfer of heat takes place from the region of high temperature to the region of low temperature.
What is heat transfer?It is a mechanism or phenomenon, which convey entropy and energy from one location to another. In order to attain thermodynamic equilibrium, the transferring of heat takes place from the warmer object to the cooler object.
The transferring of heat always takes place from the object at the higher temperature to the object with the lower temperature. The heat transfer in case of a gas is associated with a change in temperature.
Thus, the correct answer is option B, that is, high to low.

How is density different from weight and mass?
Answers
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.
Hope this helps :) if so, can I get Brainliest?
Weight is how heavy an object is/ how much force it exerts

You set up an experiment to determine the conditions needed to form the gemstones with the most clarity. You gather data from 5 different mines located around the globe, making sure to choose locations that have similar underground temperatures but different soil compositions. You discover that the minerals in the water in these locations is what determines gem clarity, Identify the independent, dependent, and controlled variables in this experiment below. 1.What is the independent variable in this experiment? * 2.What is the dependent variable in this experiment? * 3.What is the controlled variable in this experiment? i really need help
Answers
Independent: Gem Mines
Dependent: Gem clarity
Controlled: Temperature
The values that either remains the same or change are called variables. In the experimental design, the gem mines are the independent variables, gem clarity is dependent and temperature is controlled.
What are the variables in the experiment?Variables in the experiment are the measurable and quantitative characteristics that are dependent, independent, and controlled. The independent variables are self-reliant and include gem mines that cause the other variables to alter.
The dependent variables are the conditional elements that get affected by the independent varibale and include gem clarity that depends on the soil and water minerals of the mine.
The controlled variable is the constant factor throughout the experiment and is contained so that it does not alter other variables of the experiment like the temperature.
Therefore, the temperature is a controlled variable.
