1. The problem statement, all variables and given/known data
A mole of ideal gas with molar heat capacity cv = 3/2 R is initially at 298 K and 10 L and expands (with a constant temperature environment at 298K) in a final volume of 20 L in two ways
a) isothermal and reversible
b) isothermal for a fixed external pressure 0.5 atm
Compute for each of the routes the following : ΔS, ΔSsur, ΔH, and ΔT
2. Relevant equations
3. The attempt at a solution
I can't start to solve this exercise.
Help please.
