Which phase change has more kinetic energy:boiling or melting?
Romashka-Z-Leto [24]

the phase change of boiling has more kinetic energy.

boiling is a liquid ---> gas

melting is solid ---> liquid

in a liquid, there is medium kinetic energy but when a liquid is boiled it turns into a gas and gains more kinetic energy, so there is more movement and the particles move freely as there is high KE.

in a solid, there is low kinetic energy as the particles vibrate in fixed positions. a solid gains kinetic energy when it becomes a liquid (melting) and there is medium kinetic energy.

there is a higher amount of kinetic energy when a substance is boiled.

therefore, the answer is boiling.
