evaporation
It is a change of state.
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
It is an example of change in the state of matter.
The evaporation of water is an example of a physical change, where water changes from its liquid state to a gaseous state without any change in its chemical composition.
An example of a change of state is an ice cube melting and becoming liquid water, or liquid water boiling to become steam.
Boiling (or freezing) water (the change to steam or ice).
No, a change of state is not a chemical change, for it can be changed back to its original form and their is no change in the molecular composition of the substance. A chemical change is when it cannot be changed back. The above example is an example of a physical change. Example:- ice when heated changes into water and water when cooled changes into ice.
Phase change
An example of a change of state as a physical change is the melting of ice into water. This change involves a solid (ice) converting into a liquid (water) due to an increase in temperature, but the substance itself remains the same chemically.
Change in the state of matter is physical change .A good example of physical change in matter is water that is in liquid state can become solid in frozen state as ice and vapor in gaseous state
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
An example of a change of state is an ice cube melting and becoming liquid water, or liquid water boiling to become steam.
