0.247 kg of air contained in a piston cylinder assembly. Air expands from p 7.2 bar, V- 0.0136 m to p 2.98 bar. The refation between pressure and volume during the process is p. constant. If the specifie internal energy of the gas decreases by 22.08 kJ/kg during the process, determine the heat transfer, in kJ. KE and PE effects are negligible.

0.247 kg of air contained in a piston - cylinder assembly. Air
expands from pi - 7.2 bar, V - 0.0136 m' to p = 2.98 bar. The
relation between pressure and volume during the process is pV-
constant If the specifie internal energy of the gas decreases by 22.08
aJ/kg during the process, determine the heat tranafer, in kl. KE
and PE effects are negligible.
