A decrease in the size of the substance when cooling is the Thermal Contraction.

<u>Explanation:</u>

The contraction or the shrinkage of any substance when they cool is called as "Thermal Contraction". The properties of any substance changes physically when there is a change in the temperature. There occurs some expansion or contraction of substances when they are exposed to the changes in the temperature.

All substance will tend to expand when they are heated and they will shrink or contract when they are cooled. This occurs due to the fact that when the temperature changes, the energy levels of these substances also changes. Thus when we cool any substance, then it will lose heat energy as a result of which the atoms that are present in that substance will move slow and closely.
