PLEASE HELP ME 1) What is the difference between an exothermic and an endothermic process?

2) Which changes of state are exothermic and which are endothermic

1)In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system

2)Fusion, vaporization, and sublimation are endothermic processes, whereas freezing, condensation, and deposition are exothermic processes.

In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. On the other hand, an exothermic reaction releases energy into the surrounding of the system.

Explanation:

googled it for you hope it helps.

fe 55.85 g/mol and h2o 18.02 g/mol.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
