One mole Argon gas is sealed inside a thermally isolated chamber of $\displaystyle 1$ litre. A $\displaystyle 100$ W heater kept inside the chamber is switched on for $\displaystyle 30$ seconds. What will be the rise in temperature of the Argon gas? $\displaystyle \left[\mathrm{R}=8.314 \mathrm{~J} \mathrm{~mol} \mathrm{~K}^{-1}\right]$
Official answer
(2)
240.$\displaystyle 5$ K
