Answer to Question #215631 in Physical Chemistry for shruti

Question

In a reversible compression, 1 mol of ideal gas in a piston –cylinder device undergoes

a pressure increase from 1 bar to pressure P and temperature increases from 500 K

to 1000 K. The compression path is described by PV^1.5 = constant. Heat capacity is

given by Cp*/R = 3.3 + 0.63 X 10-3 T. Calculate the final pressure and heat

transferred.

Answer 1

1000-500 = 500K

PV = C

3.93 × 7 × 1.5

41.265

= 500/41.265

= 12.12atm
