Question 437: Thermodynamics & KTG

Question

An ideal gas has molecules with 5 degrees of freedom. The ratio of specific heats at constant pressure (C
p
) and at constant volume (C
v
) is :

Accepted Answer

For ideal gas molecule with 5 degree of freedom,
C
v
= $${5 \over 2}$$ R and  C
p
= $${7 \over 2}$$ R
$$	herefore\,\,\,$$ $${{{C_p}} \over {{C_v}}}$$ = $${{{7 \over 2}R} \over {{5 \over 2}R}}$$ = $${7 \over 5}$$

Answer
