CLASSIFICATION OF MATTER
? Early Indian philosophers classified in the form of five basic elements as air, earth, fire, sky and 
water called Panch Tatva.
? On the basis of the physical state matter is classified as solids, liquids and gases. 
? On the basis of chemical composition matter is classified as pure substances and mixtures. Pure 
substances may be elements or compounds. Mixtures may be homogeneous mixtures or 
heterogeneous mixtures.

FAQs on PPT: Matter in Our Surroundings - Science Class 9

1. What are the three states of matter?
Ans. The three states of matter are solid, liquid, and gas. In solid state, particles are closely packed and have fixed shape and volume. In liquid state, particles are close together but can move and flow. In gas state, particles are far apart and move freely.
2. How does matter change from one state to another?
Ans. Matter can change from one state to another through the processes of melting, freezing, evaporation, condensation, and sublimation. Melting is the change from solid to liquid, freezing is the change from liquid to solid, evaporation is the change from liquid to gas, condensation is the change from gas to liquid, and sublimation is the change from solid to gas without going through the liquid state.
3. What is the effect of temperature on the state of matter?
Ans. Temperature plays a crucial role in determining the state of matter. Increasing the temperature generally leads to a change from solid to liquid and then to gas. Decreasing the temperature causes the reverse changes. The specific temperature at which a substance changes state is known as its melting point, boiling point, or freezing point.
4. What is the difference between evaporation and boiling?
Ans. Evaporation and boiling are both processes of converting a liquid into a gas, but they differ in terms of temperature and surface area. Evaporation occurs at any temperature below the boiling point and only takes place at the surface of the liquid. Boiling, on the other hand, occurs at the boiling point and happens throughout the entire liquid, resulting in the formation of bubbles.
5. Can matter exist in more than three states?
Ans. Yes, matter can exist in more than three states. Apart from solid, liquid, and gas, other states of matter include plasma and Bose-Einstein condensate. Plasma is an ionized gas with highly energized particles, commonly found in stars and lightning. Bose-Einstein condensate occurs at extremely low temperatures and is a state of matter where a group of particles behaves as a single entity.
