AIPMT PRELIMS 2006 Physics Specific Heat Capacities MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The molar specific heat at constant pressure of an ideal gas is (7/2)R. The ratio of specific heat at constant pressure to that at constant volume is:
A
7/5
B
6/7
C
9/7
D
4/7
Correct Answer
Option A
Detailed Explanation
The ratio of specific heats (γ) is given by Cp/Cv. For an ideal gas, Cp = (7/2)R and Cv = (5/2)R, so γ = Cp/Cv = (7/2)/(5/2) = 7/5.
