What is the ratio of specific heats of constant pressure and constant volume for NH3NH_{3}

A

1.33

B

1.44

C

1.28

D

1.67

Answer

1.33

Explanation

Solution

For NH3NH_{3}, degree of freedom f=6f = 6

Ž CPCV=γ=1+2f=1+26=43=1.33\frac{C_{P}}{C_{V}} = \gamma = 1 + \frac{2}{f} = 1 + \frac{2}{6} = \frac{4}{3} = 1.33
