Question

The apparent volume expansion coefficient of a liquid in steel vessel is a and that in aluminium vessel is be if the thermal coefficient of linear expansion of aluminium is si

Answer 1

Answer:

This 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. ... This observed expansion of the liquid is known as the apparent expansion of the liquid and is less than its actual expansion.Coefficient of apparent expansion: It is the apparent increase in the volume of liquid per unit original volume per degree rise in temperature.
