Answer to Question #123623 in Molecular Physics | Thermodynamics for Gopaul

Question

0.05 Kg of a certain perfect gas occupies a volume of 0.005 metre cube at a pressure of 10 bars and a temperature of 97 ° C.
Calculate
(a) The molar mass of the gas.
(b) Its final temperature in ° C, if the latter has an expansion until its pressure reaches 2.0 bars and a
final volume of 0.05 metre cube.
If this same gas has an expansion at constant pressure with a final volume of 0.08 metre cube and cp = 1.005 KJ / Kg.K,
determine now
(c) CV
(d) Q, the heat required
(e) W, work
