Question

What do you understand by co efficient of apparent and real expansion of liquid? How they are related to each other?​

Answer 1

Answer:

hy

Explanation:

When the liquid gets heated, it expands more and beyond its original value. We cannot observe the intermediate state. We can only observe the initial and final levels. This observed expansion of the liquid is known as the apparent expansion of the liquid and is less than its actual expansion.

mark it as brilliant list ✌

Answer 2

Answer:

Coefficient of real expansion of the liquid is defined as the ratio of real change in the volume to its original volume per 1oC rise in temperature. Its SI unit is " peroC " or " oC−1 " or " K−1 ".

Coefficient of apparent expansion of liquid is defined as the ratio of apparent change in volume of the liquid to its original volume per 1oC rise in temperature. Its SI unit is " peroC " or " oC−1 " or " K−1 ".
