1.	If the coefficient of apparent expansion of the liquid is greater than the coefficient of real expansion of the liquid, what do you infer?
Answer» Solution :We know `gamma _(g) = gamma _(s) + gamma_("essel")If gamma _(s)gtgamma _(R ) gt gamma _(s)`the COEFFICIENT of volume EXPANSION of the VESSEL MUST be negative. I.e., the material of the vessel contracts on heating.
