Solution

Correct answer is option D) Permanent and chemical change.

[1 Mark]
Chemical change:- It is a change in which the chemical composition of the substance changes because of the formation of a new substance.

Permanent change:- It is a change in which the original state of substance cannot be reattained.

When a paper burns, it turns into ash, hence a new substance is formed. And it cannot be reverted to paper. Hence conversion of paper to ash after burning is a permanent and chemical change.

Q. Matter undergoes a change. The changes are of two types: Physical and chemical change.

A physical change is a change that involves only a change in the physical state of matter. Its chemical properties remain the same. Usually increasing the temperature or applying pressure or both bring about a physical change. On reversing the condition, that is reducing the temperature or reducing the pressure or both, the original state of matter is restored. In other words, physical changes are reversible.

A chemical change is a change that involves a change in the chemical composition of matter. A new substance is formed. In a chemical change, new chemical and physical properties of the substance are formed. In a chemical change, the chemical and physical properties of the substance formed will be different from the original substance.
