Thermodynamics Question 282

Question: On P-V coordinates, the slope of an isothermal curve of a gas at a pressure P=1MPa and volume F=0.0025m3 is equal to400MPa/m3 . If Cp/Cv=1.4, the slope of the adiabatic curve passing through this point is:

Options:

A) 56MPa/m3

B) 400MPa/m3

C) 560MPa/m3

D) None of these

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Slope of adiabatic curve =γ× Slope of isothermal curve =1.4×(400)=560MPa/m3
