Which explanation correctly describes the phase change in the graph? .
This is an exothermic reaction that involves melting.
This is an exothermic reaction that involves freezing.
This is an endothermic reaction that involves vaporization.
This is an endothermic reaction that involves condensation.

HELP ME PLEASE!!!!!!!

Respuesta :

Answer:

Endothermic. Endothermic phase changes take in heat from the surrounding environment; they include melting, sublimation and boiling. ... For example, the forces that hold iron atoms together are strong, so it takes high temperatures to melt iron.
