An ideal gas is that which

A box contains x molecules of a gas. How will the pressure of the gas be affected if the number of molecules is made 2x?

In a gas equation, PV = RT, V refers to the volume of:

The relation between volume V, pressure P and absolute temperature T of an ideal gas is PV = xT, where x is a constant. The value of x depend upon

The density of an ideal gas

The average velocity of the molecules in a gas in equilibrium is

Choose the only correct statement from the following 

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.

The universal gas constant has the units
