$A$ 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?

What is the value of the ratio of density $(d)$ to molar mass $(M)$ for an ideal gas?

$A$ balloon contains $2.27 \ L$ of air and has a pressure of $1.013 \times 10^5 \ Nm^{-2}$. The balloon rises to a certain height and expands to a volume of $4540 \ mL$. What is the final pressure of air in the balloon?

The density of a gas $A$ is three times that of a gas $B$. If the molecular mass of $A$ is $M$,the molecular mass of $B$ is:

Which of the following laws is followed by a hot air balloon used for sports and meteorology?

$A$ gas occupies $2.5 \ L$ at $0 \ ^oC$ and $1 \ atm$ pressure. If the pressure is increased to $1.5 \ atm$ and the gas is transferred to a $2.0 \ L$ container,what will be the change in temperature in $^oC$?
