Does the pressure of a gas decrease more rapidly or less rapidly when expanding adiabatically than it would when expanding isothermally?
A) More rapidly.
B) Less rapidly.
C) The pressure decreases at the same rate in both cases.
D) The pressure increases in an adiabatic expansion.
E) The pressure increases in an isothermal expansion.

Quizplus · Accepted Answer

In an adiabatic expansion, a gas does work on its surroundings without exchanging heat, causing its internal energy to decrease, which results in a more rapid decrease in pressure compared to an isothermal expansion where the temperature (and thus internal energy) remains constant due to heat exchange with the surroundings.
