What is the mealting point?
Melting point and freezing point: 0 degree Celcius(273 Kelvin or 32 degrees Fahrenheit) it's a point where the substance is turned into solid state
How do you identify a pure substance?
1. Check the melting point or boiling point of the substance. E.g. it is known that the boiling point of water is 100 degree celcius. It a sample of water boils are 101 degree celcius, the sample is impure. 2. Check if melting or boiling occur over a range of temperatures. E.g. if water boils from 101 to 103 degree celcius, then it is impure because pure water boil exactly at 100 degree celcius. 3. Perform paper chromatography. If the sample has only one spot on the chomatogram then it is pure substance.
How does Table salt changes to a liquid at 808 degrees?
It gets hot.
What is the temperature at which a substance changes from a liquid?
That depends on many variables. Firstly from a liquid to a solid or a liquid to a gas? If solid, water will freeze at 0 degrees celcius. Other liquids vary. Some can be very hot and still solid, others very cold and still solid. And Vise VersaHope it helped!
The temerature at which a substance changes from solid to a liquid?
It all depends on what the solid is to start with. For example, chocolote has a melting point of only 94 degrees F where as steel has melting point of 2400 degrees F.
What is the melting point of Crystal?
1,650 degrees celcius
What is the melting point for TeO3?
TeO3 Tellurium Trioxide has a melting point of 430 degrees Celcius.
What is the melting and boiling point for calcium?

What is the melting point of a banana?
-78 degrees celcius I know it’s confusing
How many degrees is the melting point?
The melting point of a substance varies according to the properties of that substance
Freezing point of pure substance 21 degrees what is the melting point?
The melting point would also be 21 degrees because the freezing point and melting point of a pure substance is exactly the same.
What is the degrees of the melting point?
Every substance has a different melting point, which means that each substance changes from solid to liquid at a different temperature called the melting point of that substance. The nmelting point of water is 0 degrees celsius.
If the freezing point of a particular substance is 52 degrees celsius then what would its melting point be?
The freezing point and melting point of a substance are the same, so the melting point would also be 52 degrees celsius.
Does wax have a high melting point?
It has a melting point between 31 degrees Celsius and 80 degrees Celsius, depending on the materials used.
What is the melting point of Zinc Metal?
The melting point of zinc is 692.68 K (787.15 �F) 420 C or 419.73 C
What are the melting and boiling points of different substances?
At 1atm, the melting point of H2O(water) is 0 degrees celcius and the boiling point is 100 degrees celcius. Carbon dioxide's boiling point is at -25 degrees and so its meting point. Since it crystallises and sublimates, it has no liquid form. The boiling- and melting points of elements/compounds depend on the amount of pressure exerted on the element/compound. Generally, the higher the pressure, the higher the boiling and melting points. All except for water, gallium and bismuth. These substances' melting point decreases as pressure increases.
