Solution

The correct option is A
chemical, physical

Generally isotopes of an element have similar chemical properties but different physical properties. This is due to the fact that the number of electrons and protons in all the isotopes of an element are same and hence they have similar chemical properties. But due to different mass number they exhibit different physical properties.

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 :

Q. Which of these is a chemical change?

(b) A substance in a different state but similar chemical properties is formed.
(c) The molecules of the substances do not undergo any change.
(d) A substance with a different shape and size but similar chemical properties is formed.
