Question 379: Properties of Matter

Question

The molar specific heats of an ideal gas at constant pressure and volume are denoted by C
p
and C
v
, respectively. If  $$\gamma $$ = $${{{C_p}} \over {{C_v}}}$$ and R is the universal gas constant, then C
v
is equal to

Accepted Answer

In case of ideal gas
C
p
Ã¢ÂÂ C
v
= R
but $$\gamma $$ = C
p
/C
v
So, $${C_v} = {R \over {\gamma  - 1}}$$

Answer

$${{\left( {\gamma  - 1} \right)} \over R}$$

Answer

$$\gamma R$$

Answer

$${{1 + \gamma } \over {1 - \gamma }}$$

Answer

$${R \over {\left( {\gamma  - 1} \right)}}$$
