Please can anybody provide the derivation for coefficient of cubical expansion in terms of mass of the liquid changing with temperature...

Dear student,

First of all, mass of a liquid does not change with temperature from law of conservation of mass. Perhaps the density would change because of changing volume, but not mass. Also the coefficient of expansion does not depend upon mass.

HELLO THERE!

Mass is the amount of matter present in the body. When you increase or decrease the temperature of the body by applying/taking heat, the mass of the body does not change!

The density changes of course (change in density is inversely proportional to the change in temperature). That is, when you increase the temperature, the volume increases. Mass remains constant.

Density = Mass / Volume

An increase in volume results in decrease in density as they have an inverse relation.

Hope you got your answer.

Thanks!
