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?

Options:

Answer:

Solution:

Given $Δ U = 5000$
$n = 4$
$Δ T = (500 - 300)$
Using $Δ U = n C_{v} Δ T$
$5000 = 4 \times C_{v} (500 - 300)$
$C_{v} = 6.25$ $J k^{- 1} m o l^{- 1}$
