Can a Gas Remain the Same Temp When Compressed?

[Sleestak]

So today I came across this question:
2) CHEMISTRY Multiple Choice Which of the following statements is NOT true:

W) an ideal gas cannot undergo condensation
X) the less mass a particle has, the faster it will effuse
Y) when a gas is compressed, its temperature always increases
Z) a gas is easier to compress than a liquid

ANSWER: Y) WHEN A GAS IS COMPRESSED, ITS TEMPERATURE ALWAYS INCREASES

I just can't think of a case where this would be false. Is it possible for a gas to remain the same temperature or even cool when it is compressed?

It depends on whether you compress the gas adiabatically or not. If you compress it infinitely slowly is will equilibrate with the outside temperature and its temperature will not increase.
