Passage / Comprehension

An amount $Q$ of heat is given to ideal monoatomic gas in a process in which the gas performs a work $\frac{Q}{2}$ on its surrounding

Molar specific heat capacity of gas is

Answer:

Solution:

First law: $Q = W + Δ U = \frac{Q}{2} + Δ U \Rightarrow Δ U = \frac{Q}{2}$ .

$\frac{3}{2} R Δ T = \frac{Q}{2} \Rightarrow Q = 3 R Δ T, so C = \frac{Q}{Δ T} = 3 R .$
