Answer:
Hypothesis may be defined as the proposed explanation of the particular phenomena. Any statement in the science can be made hypothesis only if it is tested by the scientific experiments.
The nick hypothesis can be tested by measuring the melting point of the wax and chocolate. The similar conditions are used for measuring melting point of both wax and chocolate. The substance that melts early than the other substance has lower melting point. The chocolate melts early than wax and thus wax has higher melting point than wax.
