Exothermic and endothermic: Common processes and solved examples | Chemistry | Khan Academy

Many processes that happen in daily life, give out heat or take in heat, for example, respiration, photosynthesis, etc. Let's categorize them as exothermic or endothermic reactions.

Can we say that when bond breaks the process is endothermic and when bond formed exothermic .

[@Anon4522csw]

Thank you ! Am having my exams the week after and am really glad i came across ur video!

Is digestion exothermic or endothermic?

[@servantoftheexpander9688]

Digestion isn't a chemical reaction; it is a process- the process of breakdown of food. But during that process we might have a lot of chemical reactions going on. Some might be endothermic, and some exothermic. But i haven't studied enough to give you some examples. Your question, However, is curious and interesting because you are trying to see the connection between biology and chemistry- a good thing for a mind,indeed!

Bro photosynthesis mein last mein water bhi release hota hai

Decomposition of vegetable matter how exothermic

[@rathishmuthraj4540]

I think it's because it gives energy to soil when it's decomposed?

[@BabitaSharma-tj8tk]

Thanks bro 🥹🫶🏻💓

[@dablugupta2222]

Nice
