Question

Supposing the distance between the atoms of a diatomic gas to be constant, its specific heat at constant volume per mole (gram mole) is

• A. $\frac{5}{2}R$
• B. $\frac{3}{2}R$
• C. R
• D. $\frac{1}{2}R$

Answer 1

Answer: (A)

$\frac{5}{2}R$

Answer 2

$C_{V} = \frac{f}{2}R$; for diatomic gas$f = 5$

Ž$C_{V} = \frac{5}{2}R$
