A cylinder of fixed capacity of $\displaystyle 44.8$ litres contains helium gas at standard temperature and pressure. The amount of heat needed to raise the temperature of gas in the cylinder by $\displaystyle 20.0^{\circ} \mathrm{C}$ will be :
(Given gas constant $\displaystyle \mathrm{R}=8.3 \mathrm{JK}^{-1}-\mathrm{mol}^{-1}$ )
Official answer
(3)
$\displaystyle 498$ J
