Liquids have no definite shape as they take up the shape of the container. Thus, we can say a liquid has no shape of its own but rather has the shape of the container in which it is filled.
2 is correct
When the atmospheric temperature is increased, it also will increase the boiling point of the liquid
3 is correct
This is an extension of the statement 2. While we decrease the atmospheric pressure, we are also decreasing the boiling point
4 is incorrect
A liquid have a definite volume. When we say a volume is definite, it means the volume is fixed and does not change. The volume of liquids is definite for a particular mass of the liquid and does not change
Freezing: Liquid turns into solid. Evaporation: Liquid turns into gas. Condensation: Gas turns into liquid. Sublimation: solid into gas. Deposition: Gas into solid.
