Question

The average kinetic energy of the particles of a gas is ______ proportional to ______.

A. inversely, the particle mass
B. directly, the square root of the rms speed
C. inversely, the square of the rms speed
D. directly, the rms speed
E. directly, the square of the rms speed

Answer 1

The average kinetic energy of the particles of a gas is B) directly proportional to the square of the rms speed.

Step-by-step explanation:

The average kinetic energy of the particles of a gas is directly proportional to the square of the rms speed.

This means that as the rms speed of the gas particles increases, their average kinetic energy increases by a factor equal to the square of the speed.
