exothermic or endothermic? (2 Viewers)

[jane1820]

if the test tube gets hotter is it exothermic or endothermic?

bc if u think abt it logically it would be endo since it is absorbing heat causing the test tube to get hotter but an exo is releasing heat causing the test tube to get colder
is it not?

i googled n it gave exo but it doesnt click w me bc the above is my logic of it

It's an Exothermic reaction. In an exothermic reaction, energy is released to the surroundings, typically in the form of heat, which would make the test tube feel warmer.

but wouldnt an endo also make the test tube hotter bc it absorbs heat?

but wouldnt an endo also make the test tube hotter bc it absorbs heat?

No. An endothermic reaction absorbs heat from its surroundings to proceed, which means it takes in heat from the environment (in this case, the test tube and its contents). As a result, the surroundings (and the test tube) lose heat, which often makes the test tube feel cold.

Wow... why aren't you taking chem next year?

Wdym. Endo and exothermic reactions is like yr8 science.

I thought it was yr 10? But the way you explain it suggests that you're really confident with it, idk though it's your call

I was going to take chem but then I kinda doubted myself after my poor semester 1 marks

Actually same, I think it's because knowing the theory isn't enough for chem, you need to know how to approach questions effectively

literally its yr 8 i just got confused bc in my logic its: absorbs heat ----> hot

if it absorbs heat why the fuck would the tube get hotter??

 

[Shavi Masee]

this shit is confusing me, i don't wanna do chem next year anymore.

 

[gooner]

if that shit is confusing you might wanna go back to year 8 science

 

[Shavi Masee]

I probably should lol

 

[jane1820]

if it absorbs heat why the fuck would the tube get hotter??

bc its absorbing heat?

if the test tube started normal temperature n started absorbing more and more heat it would become hot bc its absorbing heat

idk if im explaining it right but thats my logical thinking of it

i didnt mean the test tube i meant the solution itself, where is it gonna get the heat from, closest thing to it is the test tube

understandable but like do yk what i was trynna say like u get what i was trynna say without agreeing?

Thing is, heat isn't the same as temperature, it's simply a form of energy (thermal energy). When the substance inside the test tube absorbs heat in the chemical reaction, the thermal energy is converted into chemical potential energy that is "stored" inside the molecular bonds. This is because chemical reactions require the input of energy to form chemical bonds. When these bonds are broken, that's when the energy gets released. Think of the test tube as the environment around the substance, and the substance is absorbing energy from it.

Also, I'm pretty sure this is correct, but I haven't done chemistry in a year and so I might be wrong

No cause of the Pythagorean theorem we have to put exothermic² and then endothermic² so then the hypotenuse would be 87
