Question

Which process is associated with an increase in kinetic energy, and what experimental evidence supports this?

A. the transition period during which a solid is changing state into a liquid; its temperature is remaining constant
B. the period during which a solid is not changing state; its temperature is increasing
c. the period during which the gas is not changing state; its temperature is decreasing
D. the transition period during which a liquid is changing to a gas; its temperature is remaining constant

Answer 1

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

Step-by-step 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.
