Does matter change from solid to liquid at freezing point or at melting point?
Matter changes from solid to liquid at its melting point, because this change is called melting. Freezing point is about the same as melting point, but it can be slightly lower, so melting point should always be used.
When are the terms melting point and freezing point used?
When determining the melting point or the freezing point of something....that is when they are used....
What is the function of melting point apparatus?
Fisher-Johns apparatus is mainly used to measure the boiling point
What is a gray metal with a high melting point used in incandescent lights?
Tungsten is a metal with a high melting point that is often used in incandescent lamps.
Why does the temperature become constant at the point of melting till the whole substance of a solid melted?
That happens because any heat that is added to that melting material will be used to cause further melting, until there is nothing left to melt, at which point the added heat can raise the temperature. A solid melts at its melting point; it does not get hotter than the melting point without melting, that's why it is the melting point.
Why is cryolite used in the manufacture of aluminium?
It's used as a flux. It melts at a significantly lower temperature than aluminum oxide ores, but they will dissolve in molten cryolite. This means less energy is required to extract the aluminum from the ores than if they had to be heated to their melting temperatures.
What temperature does it have to be to melt a soup can?
Most soup cans are not aluminum- they are tin plated steel. While the exact melting point will vary with the alloy used, it is ABOUT 1,350 degrees Celsius. It is MUCH higher than the melting point of aluminum.

Is cast iron the best material for an electromagnet?
So far it's very good however very heavy, aluminum can be used but has a klow melting point.
Why can't copper wire used as a fuse wire?
Metal with a lower melting point is preferred for fuse wire to reduce the risk of fire.
Why is the melting point determination not used to find the melting point of inorganic compounds?
Because it has a very high melting point, and therefore we do not have the ability to be measured.RegardsDr. Mahmoud Hassouna

Under what circumstances was fluorine discovered?
Georgius Agricola discovered fluorine in 1529. It was originally used in the smelting process to lower the melting point of metals.
What are the problems with ar15 platformed weapons?
The direct impingement system requires a fair amount of maintenance. Gas piston uppers have problems with carrier tilt. The 5.56x45 cartridge isn't as powerful as the larger caliber cartridges it replaced. The aluminum used in the receivers has a lower melting point than steel.
What is a gray metal with a high melting point used in incandescent lights?
Tungsten is a metal with a high melting point that is often used in incandescent lamps.
Where is used?
It is used to seperate substances of different melting point
