A stationary mass of gas is compressed without friction

Asked by admin @ in Physics viewed by 274 People

A stationary mass of gas is compressed without friction from an initial stage of 0.3 m 3 and 0.105 mpa to a final state of 0.15 m3 , the pressure remaining constant. There is a transfer of 37.6 kj of heat from the gas during the process. How much does the internal energy of the gas change?

Answered by admin @


Answer:

Explanation:


Solution :

ΔW=−105×(0.15−0.3)KJ=+15.75KJ

Δq=−37.6KJ

∴ΔE=ΔW+Δq=−37.6+15.75=−21.85KJ
