 # ICSE Class 8 Physics Syllabus

Class 8 is considered to be the first step we take towards the preparation for the class 10 board exam. Learning and understanding the concepts of physics right from the beginning is essential to score well and also to get acquainted with the complex topics that are most likely to arise in higher classes.

The Syllabus of ICSE Class 8 Physics is given below:

### Theme 1: Matter

Kinetic Theory of Matter.

1. Three states of matter in terms of movement of particles.
2. Energy content in the three states of matter.
3. Change of state in matter using the Kinetic theory:
• Boiling
• Vaporization
• Melting
• Fusion
• Evaporation
• Condensation
• Sublimation
• Deposition
• Freezing
4. Change of state diagrams (using the terms mentioned above).

### Theme 2: Physical Quantities and Measurement

1. Density
• Units of density in various systems of units and relation between them.
• Finding density of regular solids.
2. Relative Density
• Definition
• Relation with Density
3. Measurement of Density of Fluids:
• Basic Concept
• Concept of Flotation and sinking of a substance (relate to density)
• Comparison of densities in the three states of matter.

### Theme 3: Force and Pressure

1. Turning effect of force(moment of force): concept, definition and calculation
2. Pressure:
• Definition
• Unit
• Factor affecting pressure
• The pressure exerted by liquids (Qualitative only).
• The pressure exerted by gases – Atmospheric pressure (Qualitative only).

### Theme 7: Sound

1. Sound as a longitudinal wave
2. Terms – amplitude, Time period and frequency
3. Pitch and Frequency
4. Loudness and Amplitude
5. Unit of loudness (decibels)

### Theme 8: Electricity
