When $16 \, g$ of oxygen and $3 \, g$ of hydrogen are mixed at $760 \, mm$ pressure and $0 \, ^\circ C$,the total volume of the mixture will be approximately:

An open vessel at $27\,^{\circ}C$ is heated until $3/5$ of the air in it has been expelled. Assuming the pressure remains constant,what is the final temperature of the vessel in $^{\circ}C$?

The molecular weights of $O_2$ and $SO_2$ are $32$ and $64$ respectively. If $1 \, L$ of $O_2$ at $15 \, ^\circ C$ and $750 \, mm$ pressure contains '$N$' molecules,the number of molecules in $2 \, L$ of $SO_2$ under the same conditions of temperature and pressure will be

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

If $P$ is pressure and $\rho$ is density of a gas,then $P$ and $\rho$ are related as

For an ideal gas,the volume-temperature graph at constant mass is shown below. What is the correct order of pressure?
