Answer: Option B. -> Evaporation
:
B
Evporation is the physical process through which a liquid converts to a gas on absorbing heat. For example, liquid water from oceans, lakes, rivers and other water bodies, undergoes evaporation (changes into gas)by absorbing heat from the Sun.

Answer: Option B. -> Liquids are easily compressible.
:
B
Molecules of a liquid are loosely packed due to which it doesn't have a definite shape. But, the force of attraction between the moleculesis strong enough that it has a definite volume and doesn'tcompress easily.

Answer: Option B. -> False
:
B
The force of attraction between the particles of gas is very weak compared to solids and liquids. The particles in gases are freely suspended which allows them to flow freely.

Answer: Option D. -> It has a definite shape.
:
D
Liquids have no definite shape because the molecules present in a liquid are loosely packed. So, the molecules tend to move freely.

Answer: Option B. -> False
:
B
Solids havea definiteshape and size because the force of attraction between the molecules is very strong compared to gases and liquids.

Answer: Option C. -> solution
:
C
Solution is a homogeneous mixture of two or more substances. In a sugar solution, sugar gets uniformly mixed withwater.
