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 in 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 Vertical side walls is becauseA. momentum change per collision is doubled while the frequency of collision remains constantB. momentum change per collision remain constant while the frequency of collision is doubledC. momentum change per collision and the frequency of collision both are increasedD. none of these two physical quantities are changed. It is due to some other reason. |
