piston and cylinder

A piston and cylinder containing 0.25 kg of helium at 278K receiver heat at constant temperature until the pressure is two third of its original value, find the heat added and the work.





















































































Piston-cylinder
vol = 0.2 m^3
p = 140 kpa
t = 283 k
compressed in polytropic process to
p = 700 kpa
t = 453 k
its an ideal gas, constant heat capacity (cv=0.3122)
Calculate work and heat.
