How you can determine the melting point of a compound using capillary tubes and a digital melting point apparatus that need to be calibrated each time of use?
Melting points are ranges usually. It starts when the first crystal of the substance being tested melts and ends when the last crystal melts. Therefore the smallest sample possible and the slowest rate of heating will give the most accurate melting point.
The temperature at which a solid melts is called?
melting point
What apparatus can be used to determine the melting point of sugar?
1) Experiment. 2) Ask the question on here. "What is the melting point of sugar?" *)I'll save you the trouble, though. The melting point of Table sugar (sucrose)= around 366.8°F or 186°C
What is difference between melting point and drop melting point?
No basic Difference between melting point and Drop point.
What becomes solid above the melting point?
assuming it is its own melting point NOTHING which is why its a MELTING point
How do you determine the melting point of dibenzylideneacetone?
Get melting point apparatus; determine.
What are the applications of finding the melting point of an organic compound?
To check the purity of the organic compound.
What is Abel's apparatus and how does it function?
Abel's flash-point apparatus is a petroleum-testing apparatus for determining the flash-point. It is used for the purpose of determining the flammable point of a number of petroleum products. This apparatus is suitable for determining the close cup flash point of petroleum and mixtur
How do you measure the melting point of a solid that melts above 100?
the use of a stirred oil bath, an electrical heating element, a thermometer and a capillary tube along with a magnifying glass is usually used for determining the melting point of crystalline solids. All of these may be found handily contained in a Hoover apparatus.
Why silicon use in melting point apparatus?
The silicone oil is not flammable, has a good thermal conductivity, is thermally stable.
How fast do you heat the sample when determining a melting point?
The apparatus used for determining the melting point will heat the sample at an appropriate rate. All you need to do is watch and note the point at which the sample melts, as should be demonstrated to you by your lab supervisor.
Why silicone oil is used in melting point apparatus?
The silicone oil is not flammable, has a good thermal conductivity, is thermally stable.
What is the function of the golf apparatus?
What is the main function of the Golf apparatus
Does the melting point and freexing point change depending on the mass?
No; melting/freezing points do not change as a function of mass, as long as the mass maintains constant composition.
Does melting point and boiling point of liquid changes from altitude to altitude?
The boiling point depends on altitude (pressure). The effect on the melting point is not significant.

How do you calibrate a fisher Johns melting point apparatus?
Try to get some melting point standards and use those to calibrate. Unfortunately, because they use mercury thermometers Fisher Johns have become obsolete. Electronic (digital) units are available as replacement.
