Solution

The correct option is A
Physical change

This is a typical case where we get to see the cooking which ideally lead us to believe that we are witnessing chemical change. Incidentally the colour which chef Mehboob is using remains as it is. There is no change in the original colour he has used and water goes through evaporation. The answer is physical change.

Changing state of water is a chemical or physical 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.

In a chemical change, the properties that change are :
