Liquids and solids expand with increasing temperature, because the kinetic energy of a body’s atoms and molecules increases. Explain why some materials shrink with increasing temperature.
Step 1 of 3
The some material like scandium tri-fluoride shrinks after heating. The main reason behind it is twisting of octahedral-molded units in structure of the atom.
The atomic vibration in crystal is directly proportional to the square of distance between the two atoms. But some material does not follow this rule. In scandium tri-fluoride, the vibration inside the crystal is proportional to the forth power of the separation between the atoms. This is the reason why some material show negative thermal expansion coefficient.
