Here's my problem:(adsbygoogle = window.adsbygoogle || []).push({});

An ideal gas is allowed to expand freely into an evacuated chamber.

The gas is at a pressure of 5 bar and a temperature of 45 degrees Celsius.

Find the final temperature and pressure of the gas.

Find the entropy produced.

W=0, Q=0, dU=0, and dT=0. So the final temp. is 45 degrees Celsius.

I need pressure at final state though...

dU=0 implies that u1=u2. But I don't know what the gas is, so I can't get values for these.

Am I missing something obvious?

Please help soon!

Thanks!
