Eden Kennedy · Answer 1

Option B: the period during which a solid is not changing state; its temperature is increasing

Explanation:

The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)

Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.
