10 Questions
What is the branch of science that deals with the study of the composition and properties of matter and the changes it undergoes?
Chemistry
What are the two types of changes observed in matter in our daily life?
Physical changes and chemical changes
Define physical changes and provide an example.
Physical changes are temporary changes in which no new substance is formed. Example: Water changing into ice on freezing.
Explain the concept of chemical changes with an example.
Chemical changes involve the formation of a new substance. Example: Rusting of iron.

Physical changes and chemical changes
Define physical changes and provide an example.
A physical change is a temporary change in which no new substance is formed and the chemical composition of the original substances remains the same. Example: water changing into ice on freezing.
Explain chemical changes and provide an example.
A chemical change is a change in which one or more new substances are formed with different chemical compositions. Example: rusting of iron.
What are the characteristics of physical changes?
Physical changes are temporary, no new substance is formed, and the chemical composition of the original substances remains the same.
Study Notes
What is Chemistry
- Chemistry is the branch of science that deals with the study of the composition and properties of matter and the changes it undergoes.
Types of Changes in Matter
- There are two types of changes in matter: physical changes and chemical changes.
Physical Changes
- A physical change is a temporary change in which no new substance is formed.
- The chemical composition of the original substances remains the same.
- Physical properties like color, state, shape, and size may change.
- Example: Water changing into ice on freezing and then melting back into water when kept at room temperature.
- This type of change is reversible, meaning the original substance can be regained.
Chemical Changes
- A chemical change is a permanent change in which a new substance is formed.
- The chemical composition of the original substance changes.
