Real & Apparent Expansivity
Real expansivity of liquid is sometimes called cubic expansivity of liquid. It is defined as the increase in volume per unit degree rise in temperature. Unlike solids, liquids have no fixed length or surface area but take up the shape of the containing vessel. Therefore, in the case of liquids, we are concerned only with volume changes when they are heated.
Apparent cubic expansivity of a liquid is defined as the mass of the liquid expelled per unit divided by mass left or remaining when the temperature increases by 1oC. It is measured in K-1. Therefore,
Apparent cubic expansivity = mass of liquid expelled / (mass of liquid left x temperature rise)
