Question

If an impurityis added to the sample of pure Sulphur, how will the melting point of Sulphur change

Answer 1

The addition of an impurity to a sample of pure Sulphur can lower the melting point of Sulphur. This is due to the impurity disrupting the crystal lattice structure of the Sulphur molecules, making it easier for the molecules to overcome the forces holding them together and transition from a solid to a liquid state. The degree to which the melting point is lowered will depend on the amount and type of impurity added to the sample.
