Why do some substance exist as solids?

If specific ehat capacity of a substance in solid and liquid state is proportional to temperature of the substance, then if heat is supplied to the solid intially at -20^(@)C (having melting 0^(@)C ) at contant rate. Then the temperature dependence of solid with time will be best represented by:
