The coefficient of linear expansion of a crystal in one direction is  and that in every direction perpendicular to it is .  The coefficient of cubical expansion is :

A pendulum clock keeps correct time at 0^o C. If the coefficient of linear expansion is , then what will be the loss in time per day, when the temperature rises by t^oC ?

The coefficient of apparent expansion of a liquid in a copper vessel is C and in a silver vessel is S.  The coefficient of volume expansion is .  The coefficient of linear expansion of silver will be :

A steel sphere is to be passed through a circular brass ring.  At 20^o C the outer diameter of sphere is 25 cm and the inner diameter of the ring is 24.9 cm if both are heated together, then temperature at which the sphere will just pass through the ring will be :
(Take coefficient of linear expansion of steel= and that of brass = )

The figure below shows the plot of versus P for oxygen gas at two different temperatures.
