Show that the coefficient of area expansions `(Delta A//A)//Delta T` of a rectangular sheet of the solid is twice its linear expansivity `alpha`.

Show that the coefficeint of area expansions (Delta A//A)//Delta T of a rantangular sheet of the solid is twice its linear expansitivity alpha .

The coefficient of linear expansion of a solid depends upon

The SI unit for the coefficient of linear expansion is

Among three rods, the first two are made of same material having coefficient of linear expansion alpha_1 and the third rod is made of material of coefficient of linear expansion alpha_2 . The third rod forms the base of the equilateral triangle when the three rods are arranged to form an equilateral triangle. If the altitude of triangle remains constant at all temperatures, what is the ratio of alpha_1//alpha_2 ?

A liquid with coefficient of volume expansion gamma is filled in a container of a material having coefficient of linear expansion alpha . If the liquid overflows on heating, then

Coefficient of areal expansion of a solid is 2xx10^(-5).^(@)C^(-1) . Calculate its coefficient of linear expansion.
