Vedclass · Answer

(C) In a closed flask,the volume $(V)$ and the mass of the gas remain constant. According to Gay-Lussac's Law,at constant volume,$P \propto T$. Since the temperature increases from $300 \ K$ to $600 \ K$,the pressure $(P)$ must increase. As temperature increases,the average kinetic energy of the gas molecules increases,which leads to an increase in the frequency and rate of collisions. Since the flask is closed,no gas is added or removed,so the number of moles $(n)$ remains constant. Therefore,the statement that the number of moles of gas increases is incorrect.

In a closed flask of $5 \ L$,$1.0 \ g$ of $H_2$ is heated from $300 \ K$ to $600 \ K$. Which statement is not correct?
