At constant volume, 4 mol of an ideal gas when heated from 300 K to 500K changes its internal energy by 5000 J. The molar heat capacity at constant volume is _______.
Answer (integer)
6
Solution
$\Delta$U = nC<sub>v</sub>$\Delta$T
<br><br>$\Rightarrow$ 5000 = 4 × C<sub>v</sub>(500 – 300)
<br><br>$\Rightarrow$ C<sub>v</sub> = 6.25 JK<sup>–1</sup>mol<sup>–1</sup>
