Question: If the temperature of a gas is doubled at constant volume, what happens to its pressure? (2021)

Options:

Correct Answer: It doubles

Exam Year: 2021

Solution:

According to Gay-Lussac\'s law, pressure is directly proportional to temperature at constant volume.

If the temperature of a gas is doubled at constant volume, what happens to its pressure? (2021)

If the temperature of a gas is doubled at constant volume, what happens to its pressure? (2021)

Step 1: Understand that we are dealing with a gas in a closed container where the volume does not change.
Step 2: Recall Gay-Lussac's law, which states that if the volume is constant, the pressure of a gas is directly proportional to its temperature.
Step 3: If the temperature of the gas is doubled, it means the new temperature is twice the original temperature.
Step 4: Since pressure is directly proportional to temperature, if the temperature doubles, the pressure will also double.
Step 5: Therefore, when the temperature of the gas is doubled at constant volume, the pressure also doubles.

Gay-Lussac's Law – This law states that the pressure of a gas is directly proportional to its absolute temperature when the volume is held constant.
