Answer: D. Energy is absorbed, and kinetic energy increases.
Step-by-step explanation:
An endothermic reaction is a type of of chemical reaction in which energy is absorbed from the surrounding.
An Exothermic reaction is a type of of chemical reaction in which energy is released into the surrounding.
When a liquid boils , it converts to gaseous state by absorbing energy from surroundings.
Kinetic energy is the energy possessed by an object by virtue of motion of particles.
Thus when liquid molecules absorb energy, the molecules gain kinetic energy and start moving faster in gaseous state.
