Question

For an ideal gas, the value of γ is 1.4. Find the value of specific heats of gas at constant volume and constant pressure, take R = 2 cal/mole/K.

Solution

We have,
Ratio of specific heat, y = 1.4
R=2 cal/mole/K
Now, using the formula,
$space space space space space space space space space space straight y equals straight C subscript straight P over straight C subscript straight v equals 1.4 space space space space space space space space space space space space space space space space space space space space space space space space space space space space... left parenthesis 1 right parenthesis space space space space space straight C subscript straight P minus straight C subscript straight v equals straight R equals 2 space cal divided by mole divided by straight K space space space space space space space space... left parenthesis 2 right parenthesis space$
Solving(1) and (2), we get
C_P= 7 cal/mole/k, is the specific heat at constant volume.
and C_v = 5 cal/mole/K, is the specific heat at constant pressure.
