Question

apparent expansion of liquids

Answer 1

this question is related to thermal expansion of liquid
i.e. Vf=Vi ([email protected])
where Vf is final volume of liquid
Vi is initial volume of liquid
@ is coefficient of volume expansion
and dT is change in temperature
now
apparent change in liquid volume(dV)
=Vi@dT

Answer 2

when solids turn into liquid there is expansion because the atoms in liquid are loosely packed than that of solids which increases the volume but the overall mass remains same and thus liquid expands....
