Question

Anita conducts an experiment to see how the volume of a gas-filled balloon changes when the temperature increases or decreases over time. Which of the following statements explains the relationship between temperature and volume of a gas?

A) When temperature increases, the volume increases.
B) They are both directly proportional to pressure.
C) They are both dependent variables.
D) When temperature increases, the volume decreases.

Answer 1

The relationship between temperature and volume of a gas is described by Charles's law, which states that volume increases with an increase in temperature at constant pressure.

Step-by-step explanation:

Anita's experiment on how the volume of a gas-filled balloon changes with temperature demonstrates a principle known as Charles's law. This law states that at constant pressure, the volume of a given mass of gas is directly proportional to its absolute temperature. Therefore, the correct explanation for the relationship between temperature and volume of a gas is that when the temperature increases, the volume also increases. This direct relationship is because the increase in temperature causes the gas particles to move more rapidly, thus exerting greater pressure on the walls of the container (or the balloon in Anita's case), which results in an increased volume.
