  • The molecules of a gas move in all directions with various speeds, The speeds of the molecules of the gas increase with rise in temperature. During its random motion, a fast molecule often strikes against the walls of the container of the gas. The collisions are assumed to be perfectly elastic,i.e, the molecule bounces back with the same speed with which it strikes the wall. Since the number of molecules is very large, billions of molecules strike against the walls of the container every second. These molecules exert a sizable force on the wall. The force exerted per unit area is the pressure exerted by the gas on the walls. According to kinetic theory, the pressure of the gas of density p at absolute temperature T is given by P=1/3 pv_(rms)^2 where r_(rms) is the root mean square speed of the gas molecule and is given by v_(rms)=sqrt((3kT)/m) where m is the mass of the molecule and k is Boltzmann constant Choose the only correct statement from the following

    A
    The pressure of a gas is equal to the total kinetic energy of its molecules per unit volume of the gas
    B
    The product of pressure and volume of a gas is always constant
    C
    The average kinetic energy of the molecules of a gas is proportional to its absolute temperature
    D
    The root mean square speed of a molecule is proportional to the absolute temperature of the gas

    When a particle is restricted to move along x-axis between x = 0 and x = a , where a is of nanometre dimension, its energy can take only certain specific values. The allowed energics of the particle moving in such a restricted region, correspond to the formation of standing waves with nodes at its ends x = 0 and x=a . The wavelength of this standing wave is related to the linear momentum p of the particle according to the de Broglie relation. The energy of the particle of mass m is related to its linear momentum as E=P^2/(2m) . Thus, the energy of the particle can be denoted by a quantum number 'n' taking values 1, 2, 3, ..... (n=1, called the ground state) corresponding to the number of loops in the standing wave.
