Question 16 • Chemistry

According to the kinetic-molecular theory, the average kinetic energy of gas particles depends on which factor?

Answer
A
number of particles
B
pressure
C
volume
D
temperature

Explanation

Kinetic-molecular theory says the average kinetic energy of gas particles is directly proportional to the gas’s absolute temperature. A higher temperature means particles have greater average kinetic energy; volume, pressure, and number of particles are not the determining factor. The correct choice is temperature.
