Question

when is a change said to have taken place in a material? Explain with the help of an example​

Answer 1

Answer:

A change is said to have taken place when an object differs from its original condition with differences in its composition, appearance, position, or properties.

Example, burning of wood. When wood is burnt, it changes into ash, and ash has different properties than a piece of wood. Hence, burning of wood is a change.
