Expansion in liquid. explain it
Answers
Answer: Liquids do not have a definite shape. They take the shape of the container.Thus, we can specify a liquid by its volume. Hence, we can speak of volume expansion only for liquids. Expansion of liquids is much greater than that of solids.
Explanation:
When a liquid is heated in a container, heat flows through the container to the liquid, which 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. If we consider the expansion of the container also and measure the total expansion in volume of the liquid, then the expansion is termed as the absolute expansion of the liquid.

Answer:expansion is the increase, or decrease, of the size (length, area, or volume) of a body due to a change in temperature. Thermal expansion is large for gases, and relatively small, but not negligible, for liquids and solids.
