In a closed system, if the temperature of an ideal gas is doubled while keeping the volume constant, what happens to the pressure?
Correct Answer: Pressure doubles
- Step 1: Understand that we are dealing with an ideal gas in a closed system.
- Step 2: Know that the volume of the gas is kept 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 initial temperature is T, and it is doubled, the new temperature becomes 2T.
- Step 5: Since pressure is directly proportional to temperature, if the temperature doubles from T to 2T, the pressure also doubles.
- Step 6: Conclude that the pressure of the gas will also double.
