Let's say we are given 1.0 mol of an ideal gas, and we are given a starting temperature, and and initial pressure the gas exerts.

We are now told that the gas expands adiabatically until it reaches some other pressure, p2.

How do we calculate w and dH for this?

P, V, and T are all changing in this problem, so we can't use equations that hold the others constant.
