At $300 \ K$ temperature,the pressure and volume of a gas are $1 \ bar$ and $10 \ L$ respectively. If the pressure becomes $2 \ bar$,calculate the volume of the gas at the same temperature. (in $L$)

The density of vapours of a particular volatile diatomic species $A_2$ was found to be $10 \ mg/mL$ at $1 \ atm$ and $273 \ K$. Its atomic weight is given by: [Assume ideal gas behaviour].

Which of the following statements is false?

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

The density of ammonia gas at $27^{\circ}C$ and $3 \, atm$ pressure is approximately:
