Salt, or otherwise known as Sodium Nitrate is formed convalently, undergoing covalent bonding. Salt in general does not need a high temperature to melt, as only minimal energy is needed to overcome the covalent bonds. Unless, you're referring to another kind of salt.
Iron is a metal and alot of energy is needed to break the metallic bonds within, therefore a high temperature is required.

Do solids have a high or low melting point?
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
Will pot metal attract a magnet?
Answer:Generally, pot metal will not be attracted by a magnet. Let's dig around a bit and see what's up.Pot metal is a general term, and it is applied to cheap, readily available metals with a low melting point that are used to make "trinkets" and other metal objects that are inexpensively produced. Pot metal may be composed of different combinations of aluminum, cadmium, copper, iron, lead, tin and zinc. And before you jump on the idea that the iron in pot metal will make it magnetic, know that you would be correct if there was very much in there. Recall that pot metal is generally defined as having (among other characteristics) a low melting point. Iron has a relatively high melting point, and it is not a eutectic metal. Eutectic metals exhibit the property of having a melting point lower than that of the constituent metals used to make the alloy. Iron does not belong in this class of materials.
Does peanut butter have a high melting point or a low melting point?
Peanut butter is not a pure compound, so it does not have a specific melting point. Cold will make it harder, heat will make it softer, but no specific melting or freezing point. It is a mix of many ingredients, most of which do have specific properties, but when combined in a mix, it is just a sliding scale of consistency.
Why does a molecular crystals have a low melting point?
it tends to not form crystals
Do have nonmetals have high melting points?
Yes non metals do have high melting and boiling points. This is because they have strong intemolecular forces that are hard to overcome.A2. Their melting points vary. Obviously gases such as nitrogen and oxygen have low melting points, but Silicon (1414oC) and Diamond ( around 1700oC) are rather high. Phosphorous and Sulfur on the other hand are rather low.
Do solids have a high or low melting point?

Naphthalene has high or low melting point?
Naphthalene has a relatively low melting point of around 80 degrees Celsius.
Does polonium have a high or low melting point?
Polonium has a low melting point: 254 0C.
Would you class the melting point of Aluminium high or low?
For metals it has a low melting point compared with iron or vanadium which melt at over 2000 degrees C
Does sulfur have a high or low melting point?
It has a melting point of 113 degrees celieus
Is 63.38 c considered a high melting point?
No, this is a low melting point.
Does tin have a high or low melting point?

Is the boiling point of covalent compounds high or low?
high boiling point low melting point
