It depends on the density of the substance. The higher the density, the higher the melting point and vise versa.

Why can the boiling point and the melting point be used to help identify a substance?
The boiling and melting points are almost unique to individual substances. If it should happen that two possible substances have the same melting point, they can still be identified by the method of mixed melting points. If substances A and B have the same melting point and you mix them, the mixture will melt belowthe tabulated temperature. Thus if you mix your unknown with a sample of what you think it is, if you are right it will still melt sharply at the expected temperature, but if you are wrong it will melt gradually and at a lower temperature.
What are some examples of physical properties scientist use to tell the differences between substances?
Melting point and boiling point are two physical properties that can be used to tell the difference between substances.
Effect of impurities on melting point and melting point?
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
For what two purposes are melting points routinely used?
- melting point is a specific characteristic of a substance; consequently we can distinguish these substances knowing the melting point - the knowledge of the melting point is absolutely necessary to design technological processes, to made alloy, to use surely materials at high temperature, etc.
What is the temperature at a solid becomes a liquid?
It depends on the element, but the general name is freezing point.
What information do you need to tell if two substances are the same or different?
density , boiling point, melting point also mass & volume if you wanted to include those
When you are measuring the melting point of a mixture which consists of two unknown substances how can you find out what substances does the mixture consists of?
heat it
Three test tubes labeled A B and C contain substances with appromimately the same melting points. How could you prove the test tubes contain three different chemical compounds?
You can label the test tubes with the names or letters like A,B and C. The difference can be seen from looking at the test tubes. However; there are also tests that can help you differentiate between different substance.
What is the difference between ice melting and chocolate melting?
Ice and chocolate both melt at different temperatures, and they are two different substances.
What two uses do chemist put the melting points of substances?
- a substance can be identified after the melting point because it is a specific physical characteristic- melting points knowledge is necessary for technology

What are the two properties of iron oxide that are different from iron?
Density and melting point are different.

Explain why the boiling point and the melting point can be used to help identify substances?
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.

What is the meaning of thermodynamic melting point?
Thermodynamic melting point is the temperature and pressure at which a solid will be in equilibrium with a liquid of the same composition. It is not a single point, rather it is a two-dimensional function of temperature and pressure. For most substances, the effect of pressure is rather gradual so that large changes in pressure are required to cause any significant changes in the melting point temperature.
