The density of an ideal gas

If pressure and temperature of an ideal gas are doubled and volume is halved, the number of molecules of the gas

The absolute temperature T of a gas is plotted against its pressure P for two different constant volumes V$$_{1}$$ and V$$_{2}$$  where V$$_{1}$$ > V$$_{2}$$. T is plotted along x-axis and P along y-axis.

A volume 'V' and temperature 'T' was obtained, as shown in the diagram, when a given mass of gas was heated. During the heating process, the pressure is

Universal gas constant per molecule is called

Equation of gas in terms of pressure $$p$$ absolute temperature $$T$$ and density $$d$$ is :

The density of air at N.T.P. is $$1.293 gm/lit$$. If the pressure is tripled keeping its temperature constant its density becomes

A gas is kept at 13$$^{0}$$C in a vessel. If the volume of the gas is kept constant and is heated, the pressure will be doubled to its initial pressure at a temperature

A bubble rises from the bottom of a lake, 90m deep. On reaching the surface, its volume becomes(take atmospheric pressure equals to 10 m of water )

A cylinder contains a gas at temperature of 27$$^{0}$$C and a pressure 1MPa. If the temperature of the gas is lowered to -23$$^{0}$$ C , the change in pressure is
