Example Question #11 : Thermodynamics

What happens when an ideal gas is adiabatically compressed?

Possible Answers:

None of the other answers

The temperature of the gas remains constant

Thermal energy flows from the gas to the surroundings

The temperature of the gas increases

Thermal energy flows from the surroundings to the gas

Correct answer:

The temperature of the gas increases

Explanation:

Adiabatic means that no heat/energy is transferred. Since the gas is compressed and no heat is transferred, the volume decreases causing the pressure and temperature to rise.
