Equal lengths of different solids expand by same amount when heated equally.

Equal volumes of different liquids expand by different amounts when they are heated to the same rise in temperature.

All solids expand by the same amount when heated to the same rise in temperature.

Solids expand on heating because

An ideal gas of adiabatic exponent gamma is expanded so that the amount of heat transferred to the gas is equal to the decrease of its internal energy. Then, the equation of the process in terms of the variables T and V is

Assertion: Equal moles of different substnaces contains same number of constituent particles. Reason: Equal weights of different substances contain the samme number of contituent particles.

A bimetallic strip consists of two strips of different metals joined together that expand at same rates as they are heated.

Assertion : A solid and hollow sphere of same diameter and same material when heated through the same temperature will expand by the same amount. Reason : The change in volume us independent of the original mass but depends on original volume.

A ring, a solid sphere and a thin disc of different masses rotate with the same kinetic energy. Equal torques are applied to stop them. Which will make the least number of rotations before coming to rest?

Solids expand the least and gases expand the most on being heated.

The expansion when solid expands in two dimension
