$A$ sample of gas occupies a volume of $0.2 \, L$ at $1 \, atm$ pressure and $0 \, ^oC$ temperature. What will be its volume in $L$ at the same pressure but at $273 \, ^oC$ temperature?

State Charles' law in brief.

$A$ gas at a pressure of $2 \ atm$ is heated from $25^{\circ} C$ to $323^{\circ} C$ and simultaneously compressed to $\frac{2}{3}$ of its original volume. What is the final pressure (in $atm$)?

Two separate bulbs contain ideal gases $A$ and $B$. The density of gas $A$ is twice that of gas $B$. The molecular mass of $A$ is half that of gas $B$. The two gases are at the same temperature. The ratio of the pressure of $A$ to that of gas $B$ is

If the pressure of a gas in a closed vessel increases by $0.4\%$ when heated by $1\,^oC$,its initial temperature is ....... $K$.

$A$ container is divided into two equal parts $A$ and $B$ containing $H_2$ and $O_2$ respectively,each at $1 \ atm$ pressure. If the wall separating the two sections is removed,what happens to the pressure?
