Exothermic vs Endothermic Chemical Reactions

Learn the difference between an endothermic reaction and an exothermic reaction.
Endothermic reactions take in energy and might be cold to the touch. Exothermic reactions give off energy and will sometimes be warm or hot to the touch.

At @MooMooMath and Science, we end our videos with kindness multiplies kindness. In each of my #shorts I like to tell a quick Kindness story in order to inspire myself and others to practice kindness.
Acts of kindness make a lasting positive impact on the people around you.

So I get now exothermic reaction means releasing energy while endothermic means absorbing energy good way to put it tho thanks😊

Groovy 👍 Seems like plants could be the best factories to reduce global warming and global scarcity also. 🤔

So if humans can absorb sunlight then we can also release it too note taken

I did a little demonstration with a chemical reaction where exo and endo did not make sense, when I attempted to explain it the way I saw it, then saw the meaning on Google, I was like this is opposite. It's been a few years, at least. Thank you for explaining it with fire. Fire is the only chemical reaction that actually makes sense, using exo and endo the way it was explained by the one who put it in the science history copyright as the inventor of the theory. Naturally, it seemed like the correct answer because the reaction does not use/require external energy that seems to mean endothermic, and vice versa. Learning science is like that, until it's processed into long term memory. Backwards. You say that it's true for the product of the reaction, not the energy source. The reaction releases heat, then get's colder than room temperature. You say that is exothermic. I agree. What is the verb for the reaction requiring heat input? The energy source would then change the actual verb to a different word. The heat was created internally by the breaking of bonds. You say if it releases energy to the outside of the environment, it's exothermic; does not have anything to do with where the energy is coming from, just where it's going. Thank you. I wish that I was the one explaining the video, but I will be able to after watching yours. It will be based upon your video being the reference source.

"Well understand this" thank you.

I have to revise and because my teacher taught it badly, this is a great help

[mohamedatef]

Thanks for the video
But why in an endothermic reaction the products have high energy than the reactants?

1:25 if the ice pack, the system, absorbs the heat(energy) from the surrounding why is the ice pack the one getting cooler instead of the surrounding?

Thanks! this video realy helped i am now ready for my exam

[memoff]

photosyntesis releases heat cant absorb heat

[THEBROWNLEGACY-dw]

See you for this video but lately I'm been a bee and skibda and ohia rizz and I got Kai cenat kids and fanum just taxed me so thxs for this ohia rizzler video ❤
