Asolid is cooled to a very low temperature, assuming the mass remains constant, how if at all does this affect the density of the solid?

Question: A solid is cooled to a very low temperature, assuming the mass remains constant,how if at all does this affect the density of the solid?

Temperature is related to the kinetic energy the atoms within any given substance. Within a solid, we can therefore assume that the density will increase as the solid is cooled to a low temperature, as this will cause a loss in kinetic energy and the atoms won't be able to move as freely.

Hope this helps!.
