Question

Identify the correct statements from the following

• A. The apparent expansion of liquid depends on the expansion of material of the container
• B. The real expansion of the liquid depends on the density of the liquid
• C. The expansion of liquid with respect to the container is called the apparent expansion
• D. The expansion of water is uniform

Answer 1

Answer: (A), (B), (C)

The correct options are
A The apparent expansion of liquid depends on the expansion of material of the container
B The real expansion of the liquid depends on the density of the liquid
C The expansion of liquid with respect to the container is called the apparent expansion

A liquid is heated in a container. Heat flows through the container to the liquid. It means that the container expands first, due to which the level of the liquid falls. When the liquid gets heated, it expands more and beyond its original level. We cannot observe the intermediate state. We can only observe the initial and the final levels. This observed expansion of the liquid is known as the apparent expansion of the liquid.

The apparent expansion of liquid depends on the expansion of material of container. More the container expands, more is the apparent expansion of liquid.

The real expansion of a liquid does not temperature of container, it depends on density of the liquid.

When what is heat at $0^{o}C$ its volume decreases up to $4^{o}C$ and after volume increases. Thus expansion of water is not uniform.
