If the pressure and temperature of $4 \, dm^3$ of carbon dioxide are doubled,what will be the volume of the carbon dioxide gas in $dm^3$?

$A$ car tyre is filled with nitrogen gas at $35 \ \psi$ at $27^{\circ} C$. It will burst if pressure exceeds $40 \ \psi$. The temperature in $^{\circ} C$ at which the car tyre will burst is ............ (Rounded-off to the nearest integer)

Which effect is observed when the pressure of a gas increases?

The density of $O_{2(g)}$ is maximum at?

Density of a gas is found to be $5.46 \, g / dm^3$ at $27^{\circ} C$ at $2 \, bar$ pressure. What will be density at $STP$?

$A$ certain sample of gas occupies a volume of $0.2 \ L$ at $0 \ ^oC$ and $1 \ \text{atm}$ pressure. What will be its volume at the same pressure but at $273 \ ^oC$ (in $L$)?
