IAT (IISER) 2020 | Heat and Thermodynamics Question 2 | Physics

An ideal rigid diatomic gas undergoes expansion at constant pressure when $\Delta Q$ heat is added to it. What is the ratio of the change in the internal energy $\Delta U$ to the heat supplied $\Delta Q$ ?

$\frac{\Delta U}{\Delta Q}=\frac{3}{5}$

$\frac{\Delta U}{\Delta Q}=\frac{5}{7}$

$\frac{\Delta U}{\Delta Q}=\frac{7}{9}$

$\frac{\Delta U}{\Delta Q}=\frac{2}{3}$
