At $0^{\circ} C$,a gas occupies $22.4 \ L$. What is the temperature in Kelvin required to reach a volume of $224 \ L$ (in $K$)?

Find the moles of $O_2$ having pressure $250 \ bar$ in $500 \ mL$ vessel at $300 \ K$ temperature. $[R = 8.314 \times 10^{-2} \ bar \ L \ K^{-1} \ mol^{-1}]$

The volume occupied by $1.8 \; g$ of water vapour at $374^{\circ} C$ and $1 \; bar$ pressure will be $....... \; L$ : [Use $R=0.083 \; bar \; L \; K^{-1} \; mol^{-1}$]

Which relation represents the change in density of an ideal gas with changes in temperature and pressure?

One mole of an ideal gas occupies $12 \ L$ at $297^{\circ} C$. What is the pressure of the gas?

At the same conditions of pressure,volume,and temperature,work done is maximum for which gas if all gases have equal masses?
