Answer:
when a solid reaches the temperature of its melting point,it can became a liquid for water temperature need to be little over 0 degree . celcius (0°) ar you melt . the reverse of melting process is called freezing liquid water frezzes and bece solid ice when the molecules lose energ

Answer:
1. Evaporation, melting, sublimation, solidification or freezing are the processes involved interconversion of states matter.
2. (a) A solid changes into liquid when there is a increase in temperature ️. This process is known as melting.
(b) A liquid changes into gaseous state with increase in temperature ️. This process is called evaporation or boiling.
3. Gas to liquid is compression.
Liquid to solid is solidification.
5. Diffusion is the process in which the substance from higher concentration moves to lower concentration.
