Q168 / 180 · KCET 2018 · Physics

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

  • A
    Decreases
  • B
    Increases
  • Correct answer
    C
    Remains same
  • D
    Increses or decreases depending on the nature of gas

Solution

Kinetic energy of molecules depends only on the temperature, that is,
\( \mathrm{K} \propto \mathrm{T} \)
Therefore, if the pressure of an ideal gas is increased by keeping temperature constant, then kinetic energy of molecules
remains same.

Hence, the correct answer is option: 'C'.
