1.Using the DeHoff method, compute the change in internal energy when 12 liters of argon gas at 273 K and 1 atm is compressed to 6 liters with the final pressure equals to 10 atm. Assume argon behaves ideally and CV = 3/2·R. Show details of the entire derivation.
2.Estimate the buoyant force on 10'x10' by 2' deep balsa (SG=0.2) raft with you in it. How deep is it in the water? Be sure to draw well leveled schematic of the system.
