change of state
a phase change
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.
A change in the physical state of matter is a physical change.
This is a physical change.
A physical change is a change to a substance/object which can be easily reversed, and no new substance is formed from it (as opposed to chemical change). The state of matter is usually changed, for example, turning from a solid to a liquid. e.g. ice cube melting
Melting is an example of a phase change. The substance is going from the solid state to the liquid state.
change of 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.
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
Yes. The act of moving a substance from one location to another is a physical one. The act of changing the state of the substance from one state to another can be physical also. But the act of altering the substance by adding or subtracting one or more of its components is a chemical change.
Through friction which creates heat it can change the state of matter.
physical=A physical change does not produce a new substance. chemical= A chemical change produces a new substance. u now have the answer........
A physical state is physical and not chemical Physical Property is observed without changing a substance into another substance. Chemical property is the ability of a substance to change into different substance.
Change of state of a substance is a physical property!
physical change
One possibility is a change in state.

After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
