Mechanical Properties of Fluids
Cp and Cv are specific heats at constant pressure and constant volume respectively. It is observed that
Cp – Cv = a for hydrogen gas
Cp – Cv = b for nitrogen gas
The correct relationship between a and b is
a = 14 b
a = 28 b
a = 1/14b
a= b
A.
a = 14 b
CP – CV = R
where CP and CV are molar specific heat capacities
As per the question
a= R/2
b= R/28
a= 14b
