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

Options:

  1. It doubles
  2. It halves
  3. It remains the same
  4. It quadruples

Correct Answer: It doubles

Solution: 

According to Gay-Lussac\'s Law, if the temperature of a gas is increased while keeping the volume constant, the pressure will also increase proportionally, thus it doubles.

Questions & Step-by-Step Solutions

If the temperature of a gas is doubled at constant volume, what happens to the pressure?
  • Step 1: Understand that we are dealing with a gas in a closed container where the volume does not change.
  • Step 2: Know that temperature is measured in Kelvin for gas laws, so if the temperature is doubled, we are increasing the temperature value.
  • Step 3: Recall Gay-Lussac's Law, which states that pressure is directly proportional to temperature when volume is constant.
  • Step 4: If the temperature doubles, the pressure must also double to maintain the relationship defined by Gay-Lussac's Law.
  • Step 5: Conclude that if the temperature of the gas is doubled, the pressure will also double.
  • 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.
