Suppose there are N molecules each of mass m, of an ideal gas in a container. The x component of velocity of a molecule is denoted by `u_(x)`. The gas is enclosed using a horizontal piston of area A as shown.

If the temperature of gas is doubled keeping volume constant, we know from the gas law that the pressure will be doubled. On microscopic level this increase in pressure is because

A

momentum change per collision is doubled while the frequency of collision remains constant

B

momentum change per collision remain constant while the frequency of collision is doubled

C

momentum change per collision and the frequency of collision both are increased

D

none of these two physical quantities are changed. It is due to some other reason.

Suppose there are N molecules each of mass m, of an ideal gas in a container. The x component of velocity of a molecule is denoted by u_(x) . The gas is enclosed using a horizontal piston of area A as shown. If the piston is moved so as to reduce the volume of gas by half, keeping the temperature of gas constant , we know from the gas law that the pressure will be doubled. On microscopic level the increase in pressure on the piston is because

Suppose there are N molecules each of mass m, of an ideal gas in a container. The x component of velocity of a molecule is denoted by u_(x) . The gas is enclosed using a horizontal piston of area A as shown. The pressure of the gas can also be written in terms of momentum transferred per collision (Deltap) and collision frequency (f) on the wall of area A as
