You are adding heat/energy.
It is melting.
The process in which a solid changes to a liquid is called melting.
Liquid to gas, solid to liquid, and liquid to solid
solid to a liquid
The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.
Solid, liquid, gas, liquid, solid.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
They are physical changes.
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
"The" two changes are wrong. There are lots of different states of matter, and therefore many different possible transitions. The most commonly studied states of matter are solid, liquid, and gas; each of them can change directly to each of the others, for a total of 6 types of change.
the matter can change into liquid, solid and gas.
Gas, liquid,or solid
