JEE Main 2022 · 26 Jul · Shift 1, Physics question 43

7 mol of a certain monoatomic ideal gas undergoes a temperature increase of 40K at constant pressure. The increase in the internal energy of the gas in this process is :

(Given R = 8.3 JK−1^{-1} mol−1^{-1})

Choose one option
Answer and worked solution

Official answer: B

ΔU =nCVΔT=7×32×8.3×40=3486=nC_V\Delta T=7\times\frac32\times8.3\times40=3486 J.
