TWO QUESTIONS: 1. How much heat is needed to boil away 35 g of
water initially at 10 C? (The specific heat and heat of
vaporization of water at 4.186 kJ/kgC and 2257 kJ/kg respectively.)
2. One mole of diatomic ideal gas at initial temperature 250 K and
initial volume 5 m^3 expands adiabatically to a volume of 12 m^3.
What is the work done by the gas during the expansion? Please show
all steps.
