Question
What happens to heat during an endothermic and exothermic process?Question 24Select one:a.Both endothermic and exothermic processes release heat energy overall.b.An endothermic process absorbs heat energy, while an exothermic process releases heat energy.c.Both endothermic and exothermic processes absorb heat energy overall.d.An endothermic process releases heat energy, while an exothermic process absorbs heat energy.
Solution
The correct answer is b. An endothermic process absorbs heat energy, while an exothermic process releases heat energy.
Here's why:
-
Endothermic Process: In an endothermic process, the system absorbs heat energy from its surroundings. This means that the energy of the system increases while the energy of the surroundings decreases. This is because the system needs energy to proceed with the process, and it gets this energy from the heat in the surroundings.
-
Exothermic Process: In an exothermic process, the system releases heat energy to its surroundings. This means that the energy of the system decreases while the energy of the surroundings increases. This is because the system has excess energy from the process, and it releases this energy as heat to the surroundings.
