Question

1) What is the coefficient of apparent expansion of a liquid ? What are the factors on which the apparent expansion of a liquid depends ?
2) What is the coefficient of real expansion of a liquid ? What are the factors on which the real expansion of a liquid depends ?​

Answer 1

Answer:

⓵ The coefficient of apparent expansion of a liquid is the ratio of apparent expansion in volume to its original volume for each degree rise in temperature.

The apparent expansion of a liquid depends on the following factors :

1. Initial volume of the liquid.
2. Increase of temperature.
3. Nature of the liquid.
4. Substance of the vessel.

⓶ The coefficient of real expansion of a liquid is the ratio of actual expansion in volume to its original volume for each degree rise in temperature.

The real expansion of liquid depends on the following factors :

1. Initial volume of the liquid.

2. Increase in temperature.

3. Nature of the liquid.

Answer 2

$\red{\fbox{Answer : ♡}}$

1) Coefficient of apparent expansion: It is the apparent increase in the volume of liquid per unit original volume per degree rise in temperature. Its SI unit is "per °C" or "°C-1" or "K-1".

2) The real expansion of a liquid is equal to the sum of its apparent expansion and the volume expansion of the vessel containing the liquid.
