Linear expansion is the change in ___________when object is heated or cooled.

When an object is heated

If I is the moment of inertia of a solid body having alpha -coefficient of linear expansion then the change in I corresponding to a small change in temperature DeltaT is

Assertion : When a solid iron ball is heated, percentage increase is its volume is largest. Reason : Coefficient of superficial expansion is twice that of linear expansion where as coefficient of volume expansion is three time of linear expansion.

Name and state the law governing the expansion of gases when they are heated or cooled at constant pressure.

The density of a liquid of coefficient of cubical expansion gamma is rho at 0^(@)C when the liquid is heated to a temp T , the change in density will be

When solid is heated , its length changes according to the relation l=l_0(1+alphaDeltaT) , where l is the final length , l_0 is the initial length , DeltaT is the change in temperature , and alpha is the coefficient of linear is called super - facial expansion. the area changes according to the relation A=A_0(1+betaDeltaT) , where A is the tinal area , A_0 is the initial area, and beta is the coefficient of areal expansion. A metal disc having a circular hole at its center is heated . If the metal expands on heating , the diameter of the hole

Statement-1: A brass disc is just fitted in a hole in a steel plate. The system mst be cooled to loosen the disc from the hole Statement-2: The coefficient of linear expansion for brass is greater than the coefficient of linear expansion for steel.
