Yes, boiling point is a characteristic property of matter. It is called a characteristic property because no matter how much of a pure substance you have, the boiling point should remain the same. Therefore, it is a characteristic property of pure substances.
A pure substance is a material which contains atoms of only one kind. It has fixed physical and chemical properties like boiling point, melting point, valency, density.
If you know the melting point and boiling point of a substance, you could look them up in a table to see what substances have those melting and boiling points. In practice, there are lots of other tests you'd probably want to do in addition, because in general there's no guarantee that an unknown substance is a single pure compound.
yes they have
No, boiling points are always higher than melting points. When you turn a solid to a liquid, this process is called melting, and requires a lower temperature than boiling the substance. Take ice water for example. Ice becomes pure water at 0oC. The temperature needed to boil pure water is 100oC, which is a bigger number than zero.
Because jelly is not a pure substance and its composition can change it has no fixed boiling point. It would depend on each particular jelly.
Any pure substance has only a single boiling point. If you are getting a range of boiling points, then you are heating a mixture of substances, necessarily.
These are substances that contain only one type of atoms/molecules. For example, diamond is a pure substance. Diamonds are made of strictly carbon atoms. Melting points and Boiling points of pure substances always remain constant !
Upper fixed point is the temperature of pure water boiling at normal atmospheric pressure.Lower fixed point is the temperature of a mixture of pure ice and pure water at normal atmospheric pressure. Each thermometer has a scale containing an upper and lower fixed points depending on the use of this thermometer for specific measurements.
The presence of the impurities will cause the boiling points to rise (also the melting points to fall). When you add the impurities, the substance doesn't remain pure affecting the boiling point to increase because now, more energy is required to boil the liquid with impurities. The melting points fall because impure substances require less energy to separate the particles.

Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
You think probable to a pure stoichiometric compound.
