1. A sphere 6 ft in diameter, contains oxygen at 300 psi a and 80 o F.How many
drums 6 inch in diameter and 2 ft long, can be filled to a pressure of 50 psi a
and 65 o F? If the drums are initially with pressure of 20 psi a , Assume that
the temperature of the oxygen left in the sphere remains at 80 o F.

2. While the pressure remains constant @ 689.5 KPa, the volume of a
system of air changes from 0.567m 3 to 0.283m 3 . Find the change of
internal energy.
