Question

An ideal gas has molecules with 5 degree of freedom.the ratio of specific heat at constant pressure(cp) and constant volume(cv) is

Answer 1

In Physics heat capacity ratio is also known as isentropic expansion factor that is denoted by gamma for an ideal gas or kappa for the exponent of real gas. The heat capacity ratio is important for thermodynamical reversible processes involving ideal gases where the speed of sound depends on that factor. 

Atomicity: 
Cp ÷ Cv
1 + (2 ÷ f)

F = 5
1 + (2 ÷ f) 
7 ÷ 5

Therefore the ratio of specific heat at constant pressure and constant volume would be 7 : 5

Answer 2

Answer:

the answer is 7:5 .
