A wax pattern made in the mouth will shrink appreciably as it is cooled to room temperature because the coefficient of  thermal expansion of wax is very high.(This  is the property which describes the thermal energy transport in watts per second through a specimen 1cm thick with a cross sectional area of 1 cm² when the temperature differential between the surfaces of the specimen perpendicular to the heat flow 1⁰ K)  Co efficient of thermal expansion is defined  as the change in length  per unit of the original length  of a material when its temperature is raised 1⁰K.
