A mass of an empty density bottle is 30gwhen filled with a liquid the mass of the bottle and the liquid is 40g .on heating the filled bottle through 40 degree celscius , the mass reduces to 38g.calculate the apparent cubic expansivity of the liquid?

Answer 1

mass of empty density bottle=30g

mass of bottle+liquid=40g

heating of the filled bottle=40degree c

mass reduced when heated=3g

apparent cubic expansivity=?

volume of liquid expelled

volume of liquid*temp rise remains

40-38

[38-30]*40
