The average translational kinetic energy of gas molecules depends on
A
Temperature only
B
Number of moles and temperature
C
Pressure and temperature
D
Pressure only
Verified Correct Answer: A.
Physical Principles & Numerical Solution
Temperature only.
This means that the average kinetic energy is directly related to the gas's absolute temperature. The relationship can be defined by the equation:
K.E = \(\frac{3}{2}\)kT
where K.E = average kinetic energy, k = Boltzmann's constant, and T = absolute temperature.
