Question 52: Thermodynamics & KTG

Question

If pressure of an ideal gas is increased by keeping temperature constant the kinetic energy will

Accepted Answer

The kinetic energy of an ideal gas is related to its temperature. According to the kinetic theory of gases, the average kinetic energy of gas molecules is given by:
$$ KE_{	ext{avg}} = \frac{3}{2} kT $$
where:
$ KE_{	ext{avg}} $ is the average kinetic energy of the gas molecules,
$ k $ is the Boltzmann constant,
$ T $ is the absolute temperature.
Since the temperature is kept constant in this scenario, the kinetic energy, which depends solely on the temperature for an ideal gas, will not change.
Therefore, the correct answer is:
Option C: Not change
