Question
Write down five general properties of solids, liquids, and gases.
Advertisements
Solution
Solids:
- The molecules here are very tightly packed having negligible or very less intermolecular space.
- They have the strongest intermolecular force of attraction.
- The molecules have very small vibration about their mean position i.e. small amplitude.
- They have a definite shape and volume.
- They are generally hard and rigid.
- They are good conductors of heat.
Liquids:
- Molecules are less tightly packed.
- The intermolecular force of attraction is less than that of solids.
- The molecules here can move from one place to another
- Do not have any particular shape of their own and thus acquire the shape of the vessel.
- A particular quantity of a liquid has a definite volume at a given temperature.
Gases :
- The force of attraction between the molecules is the least.
- The intermolecular space is the largest.
- Neither has a definite shape nor a definite volume.
- The molecules move independently.
- Worst conductors of heat.
