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.
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 frezing point of salt?
6 Degrees Celcius.
What is the melting point for TeO3?
TeO3 Tellurium Trioxide has a melting point of 430 degrees Celcius.
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 many degrees is the melting point?
The melting point of a substance varies according to the properties of that substance
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.
Freezing point of pure substance 21 degrees what is the melting point?
The melting point of a substance is the same as its freezing point in a closed system. Therefore, if the freezing point of a pure substance is 21 degrees Celsius, its melting point would also be 21 degrees Celsius.
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
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 substance has the melting point of 660 Celsius degrees?
The melting point of aluminium is 660,32 0C.
What is the melting and boiling point for calcium?
The melting point for Calcium is 848 degrees celciusThe boiling point for Calcium is 1,487 degrees celcius
What is the melting point of polypropylene?
The softening temperature of polypropylene is 150 degrees Celsius. Its melting point is between 160 and 170 degrees Celsius.
How does a solid change to a liquid in science?
Solid changes to liquid when a substance reaches it's melting point. For example, water's melting point is 0 degree celcius.
At room temperature a substance with a melting point of 40 Celsius is a?
Room temperature is 25 oC so it would still be a solid. It would be 104 degrees F... So. unless the substance's boiling point is below that, it would be a solid. otherwise it would be a gas.
