Hello! I just had a question concerning thermochemistry : why do we say that when water freezes, its exothermic? I dont get it. I know exothermic is when the system releases heat to the surrounding , the surrounding absorbs that heat which increases the temperature, leading to the container to feel hot. But when water freezes , its not hot??

thank you!

      Hello, TyrannosaureBeta9806.😁

      Thank you for your question!

      During freezing, water molecules become more organized to form ice. To do this, they must lose energy. This energy is released as heat to the surroundings. That is why freezing is considered exothermic, even though the water itself does not feel hot.

      Feel free to reach out if you have any other questions!
