Answer:
D) Condensation of a gas into a solid.
Explanation:
An endothermic process is a process that absorbs heat from the surroundings.
A) Boiling a liquid.
This gives off heat to the surroundings. An exothermic process.
B) Freezing a solid.
In this process, the water releases heat to the surroundings, so it is an exothermic process
C) Condensation of a gas into a liquid.
As water vapor condenses into liquid, it loses energy in the form of heat. Therefore, this process is exothermic.
D) Condensation of a gas into a solid.
This process absorbs heat from the surrounding, hence it is an endothermic proccess.
