Q. A certain amount of an ideal monoatomic gas needs $200\, J$ of heat energy to raise its temperature by $10^{\circ} C$ at constant pressure. The heat needed for the same temperature rise of the same gas but at constant volume will be:

Kinetic Theory

Solution:

$\frac{( Q )_{ V }}{( Q )_{ P }}=\frac{ C _{ V }}{ C _{ P }}=\frac{1}{\gamma}=\frac{3}{5}$
$( Q )_{ V }=120 J$
