A certain gas with Cp 0.529 BTU/lb K and R 96.2 ft lb/lb R, expands from 5 ft3 and 80 F to 15 ft 3 while the pressure remains constant at 15.5 psia.

A certain gas with Cp 0.529 BTU/lb K and R 96.2 ft lb/lb R, expands from 5 ft3 and 80 F to 15 ft3 while the pressure remains constant at 15.5 psia. Compute T2, H, Y, S, for an internally reversible non flow process, what is the work?
