Answer: Option B. -> Gas
:
B
Gas particles are loosely packed and have large spaces between them. This means they can be compressed easily.

Answer: Option D. -> 0∘C
:
D
The temperature at which a liquid converts to a solid is called its freezing point.
The freezing point of water is 0∘C.

Answer: Option C. -> indefinite shape
:
C
Gases have indefinite shape and size. Particles of gases move around freely and have very weak forces of attraction between them.

Answer: Option C. -> Melting
:
C
Melting is a physical process through which a solid is converted into a liquid. When a solid is heated, the distance betweenthe particles increases, forces of attraction decreases. Eventually, the solid converts to liquid.

Answer: Option B. -> ice
:
B
When water is below its freezing point, water particles come closer. Their interparticle forces of attraction increases and theyform a rigid structure called ice.
