Question

What is the relationship between kinetic energy and temperature?(1 point)
Responses

As the kinetic energy of a substance’s atoms decreases, its temperature may decrease or increase.
As the kinetic energy of a substance’s atoms decreases, its temperature may decrease or increase.

Kinetic energy is the energy of motion and does not have a relationship with temperature.

Answer 1

As the kinetic energy of a substance’s atoms decreases, its temperature decreases, and vice versa.

Reason: Temperature is a measure of the average kinetic energy of the particles in a substance (for example, for an ideal monoatomic gas, average translational KE per particle = (3/2)kT).
