Negative thermal expansion

Negative thermal expansion

Negative thermal expansion 01/21/15
Some materials in this universe exhibit a very peculiar property known as Negative Thermal Expansion. Under ordinary circumstances, when heat is added to an object, volumetric expansion occurs causally. This phenomenon transpires due to the fact that temperature is simply the average measurement of the vibration of atoms, and when temperature is increased, the range of the vibrations increase proportionally due to the added energy. However, materials that exhibit Negative thermal expansion have the counterintuitive result of contracting. Materials with this property have a large domain of applications, ranging from engineering to dentistry.
