The heating curve below shows the temperature change that occurs as a solid is heated. what is occurring at segment de of the graph?
melting
freezing
boiling

What is occurring at segment DE of the graph is boiling.
At point A- We are adding temperature, from A-B we are just heating the solid molecules, from point B-C, temperature is not changing but time is elapsing(solid is melting). At Point C its completely in liquid state. From point D to E liquid molecules start to heat up and evaporation occurs. From point E-F we are just heating steam.

This is what i found “nuclear fuel is material used in nuclear power stations to produce heat to power turbines. heat is created when nuclear fuel undergoes nuclear fission. most nuclear fuels contain heavy fissile actinide elements that are capable of undergoing and sustaining nuclear fission.” i hope this you for what your looking for. can you plz mark me brainliest?
