Freezing of water is an example of a phase change from liquid to 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.
Gas liquid
liquid to solid is freezing (like putting water in the freezer and getting ice) solid to liquid is melting (leaving ice on the counter and it turns to water) liquid to gas is boiling (a pot of water on the stove) or evaporation (water slowly 'disappears' from a glass) gas to liquid is condensation (water on the outside of your cold glass on a warm day) solid to gas is sublimation (dry ice)
Deposition is the phase change that does not involve changing a liquid into a gas. It occurs when a gas changes directly into a solid without passing through the liquid phase. An example of deposition is the formation of frost on a cold surface.
When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
When water changes from a liquid to a gas, it undergoes two types of changes: a physical change called vaporization, where the liquid water molecules gain enough energy to escape into the gas phase, and a state change from liquid to gas.
Let's consider the case of ice. Ice is a solid. When heated, it gets transformed to water. Water is a liquid. Further heating changes water into gas. Thus, heat can change a solid into both liquid and solid form.

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.
These are phase changes, ice melts into water and water evaporates into a gas.
These are phase changes, ice melts into water and water evaporates into a gas.
water Water is a gas when it is steam. It condenses to liquid, becoming water. It becomes solid when it freezes, and then becomes liquid again as it melts. The entire process depends on temperature. The molecular structure of water does not change throughout all these changes.

Water can exist in three physical states: solid (ice), liquid (water), and gas (water vapor). It can undergo physical changes such as freezing (turning into ice), melting (turning into water), evaporation (turning into water vapor), condensation (turning back into liquid), and sublimation (directly turning from solid to gas).
The three phases of water are solid (ice), liquid, and gas (water vapor). Water changes from solid to liquid through melting, where heat is added to break the bonds between water molecules. Water changes from liquid to gas through evaporation, where heat is added to increase the kinetic energy of water molecules until they escape into the air.
