A rigid tank contains 2.5 lbm of R-134a, initially at 80 psia and 180 oF. The fluid is then allowed to cool until a final temperature of 45oF is reached. Calculate the final pressure and the change in internal energy (Btu) of the fluid.

For a particular reaction, ? h = -144.6 kj and ? s = -301.2 j/k. calculate ? g for this reaction at 298 k.

Blank liquids and gases exert a buoyant force on objects placed in them
