Question

Choose the correct statement about I, II and III.

• A. I and II have definite volume but III does not have this property
• B. I, II and III are interconvertible by changing the conditions of temperature and pressure.
• C. In the particles of I, freedom of movement is large
• D. Both $A$ and $B$

Answer 1

The correct option is D Both $A$ and $B$

Properties of three sates of matter:

1. Solids and liquids have definite volume whereas gases don't possess definite volume.

2. Three states of matter solid, liquid and gas are interconvertible by changing the temperature and pressure conditions.

3. Solids are rigid and have definite shape thus don't possess a large degree of freedom.

Hence, option $D$ is correct.
