Name the device by which the pressure exerted by a gas can be measured.

The pressure exerted by real gas is :-

The pressure exerted by the gas molecule is

Name the device with which atmospheric pressure is measured.

The molecular theory states that the pressure exerted by a gas in closed vessel results from the gas molecules striking against the walls of the vessel. How will the pressure change if : the temperature is doubled keeping the volume constant

Name a device in which this principle is used.

The molecular theory states that the pressure exerted by a gas in closed vessel results from the gas molecules striking against the walls of the vessel. How will the pressure change if : the volume is made half of its original value keeping the temperature constant?

The molecular theory states that the pressure exerted by a gas in a closed vessel results from the gas molecules striking against the walls of the vessel. How will the pressure change if the temperature is doubled keeping the volume constant ?

Pressure exerted by a perfect gas is equal to

Obtain Graham's law of diffusion from the expression for the pressure exerted by a gas.

Vapour pressure is the pressure exerted by vapours
