I have two problems.
What is Delta U, Delta H, q, and w for the Reversible heating of an ideal gas at constant P.
Also, what are these values for the Reversible cooling of an ideal gas at constant V.
The Attempt at a Solution
For the first equation I decided that all values would be negative except for heat which is positive. I consider this because w=-pex(deltaV) and I decided q= positive because when u are heating somethign you add heat.
for the second problem I know work=0 because the system is at constant volume. Also, q=Delta U because Delta U=q+w. q is negative because soemthing that is cooling is removing heat. I can not figure out delta H.
