It is theoretically possible for a substance to have a negative value of cubical expansivity, which means that the substance would contract rather than expand when the temperature increases. However, it is very rare for a substance to have a negative value of cubical expansivity over a significant range of temperatures.

One example of a substance that has a negative value of cubical expansivity over a limited range of temperatures is water. Water has a positive value of cubical expansivity at...

Yes, some substances have a negative value of linear expansivity, which means that they contract rather than expand when the temperature increases. This is because the expansion or contraction of a substance as a result of a change in temperature is determined by the behavior of the molecules that make up the substance.

The expansion or contraction of a substance is related to the kinetic energy of its molecules. When the temperature of a substance increases, the kinetic energy of its...
