Question

If the average movement of the particles in a sweater increases, what will happen to the sweater's temperature?

A.
It will increase.
B.
It will not change.
C.
It will change after a long delay.
D.
It will decrease.

Answer 1

A. It will increase.

When the average movement of the particles in a material increases, this typically indicates that the temperature of the material is increasing. The kinetic energy of the particles is directly related to temperature; as the particles move more vigorously, the temperature of the material rises.
