Question

The coefficient of real expansion of a liquid is The coefficient of linear expansion of the vessel is The coefficient of apparent expansion of the liquid is

Answer 1

answer:

The liquids can't be directly introduced to flame. So we need beaker or vessels to heat it. If we heat the liquid using vessels,the vessels will expand with the expansion of water. Now, if we note the change in volume from readings in the beaker, the reading will be less than real expanded volume of the liquid. As, I said that the vessel expands with the liquid. So the coefficient of apparent expansion will be lesser than the coefficient of real expansion.
