Assignment 10.1
An ideal gas absorbs 5.00 x 103 J of energy while doing 2.00 x 103 J of work on the environment during a constant pressure process.
(a) Compute change in internal energy of the gas.
(b) If internal energy now drops by 4.5 x 103 J and 7.5 x 103 J is expelled from the system, find the change in the volume, assuming a constant pressure process at 1.01 x 105 Pa.

Assignment 10.2
During one cycle, an engine extracts 2.00x103 J of energy from a hot reservoir and transfers 1.5 x 103 J to a cold reservoir.
(a) Find the thermal efficiency of the engine.
(b) How much work does this engine do in one cycle?
(c) What average power does the engine generate if it goes through four cycles in 2.5 s ?

Assignment 10.3
(a) Find the change in entropy of 3.0 x 102 g of lead when it melts at 327oC. Lead has a latent heat of fusion of 2.45 x 104 J/kg.
(b) Suppose the same amount of energy is used to melt part of a piece of silver, which is already at its melting point of 961oC. Find the change in the entropy of the silver.
