Which of the following is NOT a true statement about liquids?
Nookie1986 [14]

Answer:

4

Explanation:

1 is correct

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
