First Law - Closed Systems: Example Problems

Try to solve these problems before watching the solutions in the screencasts.

Example Problem 1

Calculate the final conditions for the adiabatic reversible compression of an ideal gas that compresses to 1 cm3. The initial conditions are:  V1 = 10 cm3,   P1 = 1 bar,   T1 = 300 K

Example Problem 2

Two containers at 350 K and 0.5-MPa pressure each contain 1.0 mol of an ideal gas. (CP = 31 J/(mol K))
Container A: constant pressure piston and cylinder
Container B: fixed volume
What is the temperature and pressure in each container after 8.5 kJ of heat are added to each?
