NOTE

STATES OF MATTER

Matter can exist in three states- Solids, Liquids and Gases. The State of matter depends on Temperature and Pressure.

 

1. SOLIDS:The molecules of solids are closely packed together. They have definite shape and volume. Their molecules are arranged in a regular pattern and held rigidly by a strong intermolecular forces

 

2. LIQUIDS: Its molecule are freer than that of solid, they have definite volume but no definite shape. They have larger intermolecular distance than solid molecules.

 

3. GASES: The cohesive force binding the gases molecules together is negligible. They have no definite shape and Volume. Their molecules are at far distance apart. They have greater speed due to the space between its molecules. Their motion is linear except when they collide.

 

EVALUATION:   1. List and explain the three states of matter

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
