Is the melting point of the alloy higher or lower than the composition

The melting point of an alloy is lower than the melting point of the substances that make it, but its hardness is higher than that of the substances that make it.

The melting point of an alloy is lower than the melting point of the substances that make it, but its hardness is higher than that of the substances that make it.University ChemistryThe answer is not certain, because: there are generally three types of alloys:(1) eutectic mixture (2) metal solid solution (3) metal compound (1) melting point is higher than that of the substances that make it.

The melting point of solid mercury is minus 117. Melting point is heating to minus 117 or cooling to minus 117. Why? Specific points

When the crystal melts, it absorbs heat at a constant temperature, which is called the melting point. Because mercury is solid, it should be heated to minus 117 degrees Celsius
