What is example of change?
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.
What can cause change of state in an object?
Processes involved in changes of state include melting, freezing, sublimation, deposition, condensation, and evaporation. Energy is always involved in changes of state. Particles of matter either absorb or lose energy when matter changes from one state to another.
What do you understand by change of state of materials?

What is same physical state?
Allotropes are two or more forms of the same element in the same physical state (solid, liquid, or gas) that differ from each other in their physical, and sometimes chemical, properties. The most notable examples of allotropes are found in groups 14, 15, and 16 of the periodic table.
What is the meaning of state in science?
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container.
