JEE PYQ: Thermodynamics Question 16

Question 16 - 2020 (08 Jan Shift 2)

At constant volume, 4 mol of an ideal gas when heated from 300 K to 500 K changes its internal energy by 5000 J. The molar heat capacity at constant volume is ___.

Show Answer

Answer: 6.25

Solution

$\Delta U = nC_V\Delta T$. $5000 = 4 \times C_V \times (500 - 300)$. $C_V = 6.25$ J K$^{-1}$ mol$^{-1}$.
