Explain 'Kinetic Molecular Theory'.

The molecular theory accounts for the pressure exerted by a gas in a closed vessel as a result of the gas molecules striking against the walls of the vessel.

How will the pressure change if the temperature is doubled keeping the volume constant?

The molecular theory accounts for the pressure exerted by a gas in a closed vessel as a result of the gas molecules striking against the walls of the vessel.

How will the pressure change if the volume is halved, keeping the temperature constant?

$60 {\mathrm{cm}}^3$ of oxygen was added to $24 {\mathrm{cm}}^3$ of carbon monoxide, and the mixture was ignited. Calculate the volume of oxygen used up.
