Question

hey guys. in.exo thermic reaction the heat is evolved out after the reaction in the form of energy so according to e=mc2 mass is destroyed in the form of heat energy .So this disprove the law of conservation of mass which says that mass can neither be created nor destroyed but here as u can see mass in the form of energy is being destroyed??don't spam dudes .only answer when u know !!explain me. ​

Answer 1

exothermic reaction comes under combination reaction .. which means heat is provided by us to any reactant . so its heat provided by us ad we r external source .. I think your doubt is clear now

we r studying this chap

Answer 2

actually many ppl understand this topic wrong ,mass can be converted to energy and vice versa but it's not completely correct according to my knowledge.Albert einstein in 1905. in his papers he published e=mc2 but I was m=e/c2 , extra info 1905 is known has miracle year ,by this equation he told that mass is another kind of energy, actually I can't define mass I can't give a identity to it ,it's actually another form of energy ,but energy and mass are related tho

now example I will give

take to balls with mass m and m so when u add

m+m = m1

so according to law of mass u know ...

but actaully m1 has less mass not equal to m+m

and this less mass u can call it has mass defect ,∆m b

so ∆m produces a energy this can be in kinetic , potential or thermal

however still research is going on

some say mass is a quantity .

hardwork lol ,don't go so much deep in this lot of confusion in this relativity theorem still..

thank you
