Water is a chemical (pretty much all matter is technically made of chemicals), so it can undergo chemical changes.
Ice itself is not particularly reactive, but if it is melted into water (physical change), it can be chemically changed in a number of ways.
These are some relatively common ones:
1. Water can be mixed with CO2 (Carbon dioxide) to form Carbonic Acid, something with a different chemical structure from water.
2. Water can undergo electrolysis to be split into its component elements, hydrogen and oxygen.
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
Dry ice goes through a physical change when it sublimates, transitioning directly from a solid to a gas without melting into a liquid. This is a physical change because the substance's chemical composition remains the same.
The spoiling of milk is a chemical change. This occurs when bacteria digest the proteins and fats in the milk, producing compounds that cause the bad smell.
The chemical reaction is interrupted.
A reversible change is when something can turn back into its original shape for example when ice is melted it turns into a liquid but then you can freeze it into a solid again do the change is reversible because it can change back into its original starter which is the ice in this case. But if you make a cake it is not reversible because all of the mixture has mixed together and it turns into one object this is called a chemical change. Also a reversible change is a physical change! Hope this helped ;)
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
The melting of ice cubes is a physical change, not a chemical change. The change involves a phase transition from solid ice to liquid water without any changes in the chemical composition of the substance.
Melting ice cream is a physical change because it has the ability to go back to it's frozen form and be ice cream again. The chemical identity of it isn't changed.
It is a Physical Change. Melting it does not change what components/elements are found in snow. It is just a phase change from solid to liquid.
think if it can be reversed. if it is easially reversed, it is most likely physical. ie. if you bake a cake, you cant make it go back to a batter, so it is a chemical change. if you freeze an ice cube, you can just melt it and it goes back to water, so its a physical change.
Water freezing into ice is a physical change because the molecules in water rearrange themselves due to a decrease in temperature, resulting in the formation of a solid structure (ice) with the same chemical composition as water. No new substances are formed during the process, making it a reversible change.
Dry ice goes through one change to make "fog", but water ice has to go through two changes to become a gas.You could use water ice to make fog, but it would have to go through the liquid phase before it evaporates or boils. But dry ice, instead of melting and evaporating, will go through what is called sublimation, which is the change of matter of solid to gas.
it's physical change

A physical change is a change in appearance or state of matter without altering the chemical composition. Examples include cutting paper or melting ice. A chemical change results in the formation of new substances with different chemical properties. Examples include burning wood or rusting iron.
