Answer: melting points are major means of identifying pure compounds.
Explanation:
A pure compound can be identified by its melting point because, a pure compound will have a sharp melting point while an impure compound will melt over a temperature range. If presented with a pure sample of an unknown solid, its melting point can tell us what the identity of the compound. Similarly, melting point analysis can show the purity of a known solid. If the known solid has a sharp melting point, then it is pure.
The thermometer operates under the concept of the Zeroth Law of Thermodynamics. The thermometer displays the temperature of its surroundings, regardless of the identity of the substance. So, if the water is 20°C, then the thermometer displays 20°C.
