oil is used when we are determining the melting point of compound higher than 100 while for those compound which have melting point less then 100 we use water bath
Liquid paraffin is used in thermostatic baths, to maintain a constant temperature.
Because it has a very high melting point, and therefore we do not have the ability to be measured.RegardsDr. Mahmoud Hassouna
Because the melting point can be very similar; also impurities change the value of the melting point.
At standard pressure: - Melting point of ice: 0 0C - Boiling point of water: 100 0C
*usually* melting point is a good indicator of a substance's purity. The technique of melting point determination is used frequently in organic chemistry labs.

Of ice and water: 32 and 212, respectively

compounds are identified because each compound have characteristically different melting and boiling points.
Silicon has a melting point and boiling point of 1414 deg C and 2900 deg C respectively.
It is not easy to be cleaned inside.

It would take hours and hours to heat the entire sample up so slowly from outside to the inside to reach the same temperature everywhere, because for a sharp melting point determination the temperature differences (outside-inside) should be as small as possible.
