At $273 \, K$ temperature and $1 \, bar$ pressure,if the volume of a gas increases by $20 \%$,what temperature is required assuming pressure remains constant (in $, K$)?

Under what conditions does an ideal gas have maximum density?

If $10^{-4} \ dm^3$ of water is introduced into a $1.0 \ dm^3$ flask at $300 \ K,$ how many moles of water are in the vapour phase when equilibrium is established? (Given: Vapour pressure of $H_2O$ at $300 \ K$ is $3170 \ Pa;$ $R = 8.314 \ J \ K^{-1} \ mol^{-1}$)

Volume of a given mass of gas at $17 \, ^oC$ is measured as $200 \, cm^3$. The volume of the same mass of that gas at same pressure and at temperature of $47 \, ^oC$ will be .............. $cm^{3}$

$A$ balloon is filled with hydrogen at room temperature. It will burst if pressure exceeds $0.2 \ bar$. If at $1 \ bar$ pressure the gas occupies $2.27 \ L$ volume,up to what volume can the balloon be expanded?

Which of the following expressions at constant pressure represents Charles's law?
