Physical Property
Definition :
A characteristic of a substance that can be observed without changing the substance into something else.
Example :
Water boiling
Solid melting
Water freezing
Volume
Color
Examples of a Physical property
Water Boiling
This is a example of a Physical Property. The water is boiling and the water is evaporating, also the temperature is changing .
Ice cube melting
This is also a example of a Physical Property. The ice cube is a solid and it is turning in to a liquid.
Water freezing
This is a example of a Physical Property. The water freezes and then it turns it in to a ice cube.

Definition ;
A change that alters the form or appearance of a substance but does not make the material into another substance

Log on fire and ashes
Baking a cake
Explosion of a firework
An explosion of fireworks
Ashes after a fire
