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 $K$)?

Pure hydrogen sulphide is stored in a tank of $100 \, L$ capacity at $20 \, ^oC$ and $2 \, atm$ pressure. The mass of the gas will be ............... $g$.

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

If the pressure and absolute temperature of $2 \ L$ of $CO_2$ are doubled,the volume of $CO_2$ would become ............... $L$.

Explain the relationship between pressure,volume,and density of gases.

An ideal gas will have maximum density when
