Section D: Short Answer Questions

 

1. What are the three states of matter? Write one example of each.

Solid – Example: Rock
Liquid – Example: Water
Gas – Example: Air

 

2. Difference between solids, liquids, and gases based on molecule arrangement:

Solids: Molecules are closely packed, cannot move freely.
Liquids: Molecules are less tightly packed, can move and flow.
Gases: Molecules are very loosely packed, move freely in all directions.

 

3. Saturated vs Unsaturated solution:

A saturated solution is one where no more solute can dissolve in the solvent.
An unsaturated solution can still dissolve more solute at the same temperature.

 

4. What happens to molecules during heating and cooling:

Heating: Molecules absorb energy, move faster, spread apart (e.g., melting, evaporation).
Cooling: Molecules lose energy, come closer, slow down (e.g., freezing).

 

5. Four physical properties of matter:

Appearance: Shape and size (e.g., ball is round)
Odour: Smell (e.g., kerosene has a strong smell)
Texture: Feel (e.g., cloth is soft, stone is hard)
Solubility: Dissolves or not (e.g., sugar dissolves in water)
