If the temperature of an ideal gas is doubled at constant volume, what happens to its pressure?
Correct Answer: Pressure doubles.
- Step 1: Understand that we are dealing with an ideal gas.
- Step 2: Know that we are keeping the volume constant.
- 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 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 also doubles.
