Dalton's law of partial pressure will not apply to which of the following mixtures of gases?

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

The density of a gas at $27\,^oC$ and $1\, atm$ is $d$. At constant pressure,at which of the following temperatures will its density become $0.75\, d$?

If $P$,$V$,and $T$ represent the pressure,volume,and temperature of a gas respectively,which is the correct representation of Boyle's Law?

In the gas equation $PV = nRT$,the universal gas constant $R$ depends on:

The temperature of a flask is increased from $27\,^{\circ}C$ to $277\,^{\circ}C$. If $0.1\,dm^{3}$ of gas bubbles out from the flask at $277\,^{\circ}C$,calculate the volume of the flask. (in $,dm^{3}$)
