What are the meterials used in fse wires?
Low temperature melting point materials like copper, aluminium, tin or lead are used to make the fuse wire. Zinc and antimony are also used because of their low melting points.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
How a termometer can be used to check the purity of a metal?
because gold or iron are metal if they are not a metal so they can not check the purity but they are metals..
Is the melting point of organic compound high or low?
Melting point is important in organic chemistry because it can be used for the identification of a compound. For pure solid organic compounds will have a small melting point range (0.5-10C),thus presence of impurity can also be find out by Melting point.
Why are boiling points of liquids usually reported along with the pressure at which the boiling point was measured?
Melting points of pure solids are reported without including the pressure. This is because it is assumed that standard laboratory conditions of 1 BAR, or 25 degrees Celsius were used.
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 properties may be used to ionic compounds?
crystal shape, high melting points, and electrical conductivity

because gold or iron are metal if they are not a metal so they can not check the purity but they are metals..
What is gold's freezing point?
1063 °C(lit.) Freezing points and melting points generally can be used interchangeably. Scientific data is reported as the melting point or mp. Purity will also effect the freezing point but very useful in determining the purity of a substance.
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student
How can laser be used in surgery?
They are used routinely for eye surgery.
Can Filtration can be used to separate mixtures based on their boiling point?
It is not possible; filtration as a separating method is based on the difference between boiling points.
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.

Melting point is important in organic chemistry because it can be used for the identification of a compound. For pure solid organic compounds will have a small melting point range (0.5-10C),thus presence of impurity can also be find out by Melting point.
