Qstn# ii-3 Prvs-QstnNext-Qstn
  • #3
    The pressure of an ideal gas is written as
    P=2E3V. Here E refers to
    (a) translational kinetic energy
    (b) rotational kinetic energy
    (c) vibrational kinetic energy
    (d) total kinetic energy.
    digAnsr:   a
    Ans : According to the kinetic theory, molecules show straight line in motion (translational). So, the kinetic energy is essentially transitional.
    Thus,
    (a) is the correct answer.
