it rains, water evaporates, it rains.

With changes in temperature.
Water is solid below o degrees celcius, and gas above 100 degrees C.
Yes, the water has turned into ice. It was a liquid but it is now a solid. You can change it back again by melting it.
when ice was solid change liquid because sun was very hot. ice will change liquid change back solid again
Change of state from a liquid to a solid and back again.
An example of a reversible change is an ice cube meting into water and then changing back to an ice cube again if frozen. Another is chocolate melting when heated and changing back to a solid when cooled.
A solid, or even a gas. And back again (improved)liquid is a state of matter, which can be a solid, liquid, or gas. therefore, liquid can be changed into a solid or a gas. to do so, just change the temperature of the matter. :-D
a physical because it becomes water again a chemical means it can not change back
Solids to Liquids (Melting) Liquids turning back into a Solid (Freezing) ((SCF))
A glass of ice water is an example of a physical change, where water changes from a liquid to a solid state as it freezes. This change is reversible, as the ice can melt back into water.
One example of a substance that can change from a solid to a vapor and vice versa is water. When water is heated, it changes from a solid (ice) to a liquid (water) and eventually to a vapor (steam). When steam is cooled, it condenses back into liquid water, and if cooled further, it freezes back into solid ice.
An example of a change that begins and ends with the same type of matter is the process of water changing from a solid (ice) to a liquid (water) and back to a solid (ice). In this process, the water molecules remain the same, just in different states of matter.
CHANGES OF STATE change of state (or change of phase) of a substance describes the change of a substance from a solid to a liquid, liquid to a vapor (or gas), vapor to a liquid, liquid to a solid, solid to vapor, or vapor to a solid. In meteorology you are concerned primarily with the change of state of water in the air. Water is present in the atmosphere in any or all of the three states (solid, liquid, and vapor) and changes back and forth from one state to another. The mere presence of water is important, but the change of state of that water in the air is significant because it directly affects the weather. The solid state of water is in the form of ice or ice crystals. The liquid state of water is in the form of raindrops, clouds, and fogs. The vapor state of water is in the form of unseen gases (water vapor) in the air
A lava lamp demonstrates a physical change. The wax in the lamp changes states from solid to liquid and back to solid again as it is heated and cooled, but the chemical composition of the wax remains the same throughout the process.
