Question: In a closed system, if the temperature of an ideal gas is doubled while the volume remains constant, 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, pressure is directly proportional to temperature at constant volume. Therefore, if the temperature doubles, the pressure also doubles.

Questions & Step-by-Step Solutions

In a closed system, if the temperature of an ideal gas is doubled while the volume remains constant, what happens to the pressure?
Correct Answer: Pressure doubles
  • Step 1: Understand that we have a closed system with an ideal gas.
  • Step 2: Know that the volume of the gas is constant, meaning it does not change.
  • Step 3: Remember Gay-Lussac's law, which states that pressure is directly proportional to temperature when volume is constant.
  • Step 4: If the temperature of the gas is doubled, this means it increases to twice its original value.
  • Step 5: Since pressure is directly proportional to temperature, if the temperature doubles, the pressure must 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.
