its a phase change
This change in the state of matter (liquid to solid) is called freezing, not melting; it is a physical change, the chemical nature of the molecules is not changed.
change of a liquid to a solid
Water changes from a solid to a liquid through melting and from a liquid to a gas through evaporation. The reverse processes are freezing (liquid to solid) and condensation (gas to liquid). These changes in state occur due to variations in temperature and pressure.
When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
A liquid will change to a solid when it freezes.
ice
yes
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.
When a solid melts or changes to a liquid. When a liquid boils or changes to a gas. or the reverse when a gas condenses to a liquid or a liquid freezes to a solid. Also it is possible for a solid to go directly to a gas without passing through the liquid stage. This is called sublimation and can occur with sulfur when heated, or ice in the winter when the sun shines on it..
They are physical changes.
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
No, freezing changes a liquid to a solid. To change a solid to a liquid you need to apply heat. The change begins when the solid reaches its melting point.
