Chemistry - Thermodynamics - 1 Question with Solution | TestHub

${\text{PV}}^{\text{5/3}}\text{=}\text{constant}\text{for}\text{He}\left(\text{γ}\text{=}\frac{\text{5}}{\text{3}}\right)$
${\text{PV}}^{\text{7/5}}\text{=}\text{constant}\text{for}{\text{O}}_{\text{2}}\left(\text{γ}\text{=}\frac{\text{7}}{\text{5}}\right)$
$\therefore \text{For}\text{the}\text{same}\text{decrease}\text{in}\text{V}$
${\text{P}}_{{\mathrm{O}}_2}<{\mathrm{P}}_{\mathrm{H}\mathrm{e}}\mathrm{}$
