What takes my teachers a week to explain this video takes 4 min Why r schools so complicated Exp algebra i have a way of solving equations easy way My teacher makes it harder
*Thanks a lot man* 😉 . These reactions has always been a lot confusing 🤦🏻♂️ *Exo -* gives out the E and makes the surrounding hotter . *Ex-* Respiration , Bonfire *Endo -* takes in the E and makes the surrounding colder . *Ex-* Photosynthesis 👍
@@P0P0_xyz288 to strengthen our concept, we should determine it is from system or surrounding. Exothermic is condition where surrounding is heater and the system is colder. There is temperature gain in surrounding cause the system is disengage calor.
Thank you so much for uploading this video, I have been struggling with chemistry for a while now and my teacher is terrible at teaching, so bad to the point I considered dropping out. This video was super helpful for me, thanks again for uploading - Sarah
For the people complaining about teachers: In our school we have sets, so we have different teachers for different classes, some teachers might take a week on that subject because of the pace of the class. So top set will move on quicker (big brain people) and bottom set will need more time to catch up (small brain people like me :D) Idk if this helps but- :)
My teacher explained that the thermometer measures surroundings too, therefore it can get hotter Simple example: reactants are 20°C + 20°C given to the surroundings that's how I understood it
Great job! But there are NO new bonds (i.e. covalent or ionic) being formed in a change of state like melting and condensing. Intermolecular forces (i.e. hydrogen "bonds" or dipole forces) are being overcome or are becoming dominant in the tug of war between intermolecular forces and kinetic energy.
Thank you very much as this helps me make my study guide. You are amazing. Even though my teacher is really good some questions in my OneNote are not directly answered. Thank you very much!
Can you please explain me how you say boiling is an endothermic reaction. As you said before, endothermic are the ones which takes energy, how the boiling is taking energy by turning liquid into gas? Isn't it releasing the energy and temperature is increase; how this isn't called an exothermic reaction?
Craft Avrila yes, but only if you are trying to describe the thermometer’s status. We are trying to figure out whether or not the reaction is endo or exothermic. Since it is releasing energy that the thermometer absorbs, it’s exothermic in nature
But I don't get it. If the snowman takes in heat from its surroundings (endothermic reaction), then shouldn't it get warmer? You say that endothermic reactions absorb heat from the surroundings, yet the temperature drops. But if something absorbs heat, it should become hotter. The reverse should also apply to exothermic reactions. If a reaction gives heat to the surroundings, shouldn't it become colder?
An exothermic reaction gives out energy to the surroundings - so it gets hotter. An endothermic reaction takes in energy from the surroundings - so it gets colder.
Ahh finally I can sleep well for my quiz. Making bonds = Exothermic Losing bonds = Endothermic because it needs more energy to break it Lame man's words are good for understanding complex chemistry
what happens to the system during an exothermic reaction, my teacher said it becomes hotter but i don't understand that because the system in giving out heat so shouldn't it cool down?
