Pressure of an ideal gas is increased by keeping temperature constant. The kinetic energy of molecules

The energy of a gas per litre is $300 \ J$. Then its pressure will be:

If the distance between molecules is doubled at a constant temperature,the pressure will become .......

$A$ sealed container with negligible coefficient of volumetric expansion contains helium (a monoatomic gas). When it is heated from $300\, K$ to $600\, K,$ the average kinetic energy $(K.E.)$ of helium atoms is

At $0 \; K$,which of the following properties of a gas will be zero?

Two gases $A$ and $B$ are at absolute temperatures $350 \ K$ and $420 \ K$ respectively. The ratio of average kinetic energy of the molecules of gas $B$ to that of gas $A$ is
