Open in App

Solution

Heat energy always flows from an object at a higher temperature to an object at a lower temperature.
The transfer of heat can cause the size of the object to increase if heat is added to it and shrink if heat is removed.
This reduction of the size of the object due to the removal of heat from it is called contraction.
Hence, Change in size of a substance when heat is taken away from it, is called contraction.
