Question

Freezing of water is endothermic or exothermic?? And give reason why ??

Answer 1

It is exothermic because in freezing water release heat to its surroundings

Answer 2

Hii There!!!

✔️When water freezes (i.e, changing from liquid to solid state) , it releases some energy in which 80 calories of heat is released when 1 gram of water is freezed.
Hence, it will be considered as an 'Exothermic Reaction'.

✔️Moreover, due to this we have to heat the ice to melt it for obtaining water. Thus, melting of ice will be an 'Endothermic Reaction'.
