Options
- ANot change
- BVary quadratically
- CIncrease
- DDecrease
Correct answer
A. Not change
Step-by-step solution
The average kinetic energy of an ideal gas molecule is given by the formula K.E. = 3 2 k_ B T , where k_ B is the Boltzmann constant and T is the absolute temperature of the gas. Since the temperature T is kept constant, the average kinetic energy of the gas molecules depends only on the temperature and remains independent of the pressure or volume of the gas. Therefore, when the pressure of an ideal gas is increased at a constant temperature, the kinetic energy of the gas does not change. Answer: Not change
