A 0.500-mol sample of an ideal monatomic gas at 400 kPa and 300 K, expands quasi-statically
until the pressure decreases to 160 kPa. Find the final temperature and volume of the gas, the work
done by the gas, and the heat absorbed by the gas if the expansion is (a) isothermal, and (b)
adiabatic.
50 grams of water at 20ºC is converted into steam at 250ºC at constant atmospheric pressure. Assuming the heat capacity per gram of liquid water to remain constant at 4.2 J/g K and the heat of vaporization at 100ºC to be 226 J/g, and using Cp/R=a+bT+cT2, calculate the entropy change of the system. a=3.652, b=1.157x10-3 K-1, c=0.142x10-6 K-2
