mole of a monoatomic gas undergoes the process $PT =$ constant. Then the molar heat capacity of the gas during the process will be equal to:

Options:

Answer:

Solution:

$PT =$ const and $T = \frac{P V}{n R} \Rightarrow P^{2} V =$ const , i.e. $P V^{1/2} =$ const. Polytropic index $x = \frac{1}{2} : C = C_{V} + \frac{R}{1 - x} = \frac{3 R}{2} + \frac{R}{1/2} = \frac{3 R}{2} + 2 R = \frac{7 R}{2} = 3.5 R$ .
