Physical changes alter a substance's physical properties like state, color, or odor without changing its chemical makeup. Examples include melting ice and blowing up a balloon. Chemical changes create new substances through irreversible reactions, such as ripening fruit that transforms its chemical structure. The document aims to differentiate and provide examples of physical and chemical changes.

2. Objectives:
At the end of the lesson, you should be able to :
1. Explain What is Physical and Chemical changes .
2.Differentiate between physical and Chemical changes .
3. Give Examples of Physical and Chemical changes.

3. Matter undergoes two types of changes
..
PHYSICAL CHANGE
CHEMICAL CHANGES .

4. Physical change
Physical change is a type of change where the physical
properties of matter change. A change of state of matter,
change in colour, odour, solubility, etc. all are examples of
physical change. During a physical change, neither the
composition nor the chemical nature of matter is changed.
Changes are reversible.

5. Example of Physical change
Melting of ice

6. Example of Physical change
Blowing of a balloon

7. CHEMICAL Change
A chemical change is a change of materials into another, new
materials with different properties and one or more than one new
substances are formed. It results when a substance combines
with another to form a new substance.
Changes are irreversible

8. Examples of Chemical changes
Ripening of fruits and Vegetables

9. SUMMARY

10. Evaluation

Give two another Examples for each case .
