Is freezing point of a substance is equal the melting point of the same substance?
The freezing point and the melting point both refer to the temperature at which a substance changes between a liquid and a solid state. If other conditions remain the same, the temperature at which a substance freezes is the same temperature at which it melts. Water is an every day example with a freezing point of 0C, the same temperature as it will begin to melt. Other substances such as metals have significantly higher melting points from around 200C to more than 3000C.
Three test tubes labeled A B and C contain substances with appromimately the same melting points. How could you prove the test tubes contain three different chemical compounds?
You can label the test tubes with the names or letters like A,B and C. The difference can be seen from looking at the test tubes. However; there are also tests that can help you differentiate between different substance.
Do all substances have their own boiling point and freezing point?
please correct me if im wrong but i think everything that doesnt burn has a melting point Everything has a melting point, no matter how hard or dense. Even diamonds can melt if hot enough. Not everything has a melting point. Some things never change into liquid, they go from solid to gas. Dry Ice does this at room temperature. This process is called sublimation.
Do All minerals have the same melting point True of False?
False, all minerals DO NOT have the same melting point
How can iodine have a melting point?
All substances have melting points and boiling points. A melting point is merely the temperarture at which it changes from a solid to liquid and vice versa. The boiling point of a substance would be the temperature at which it changes from liquid to gas and vice versa.
Can the melting and freezing point of a substance be the same?
For water and some other substances, the answer is 'Yes'.
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.

How is the melting point of asolid and boiling point of a liquidaffected when impurities are added to the substances?
Adding impurities lowers the melting point and raises the boiling point.
Is melting point a physical proporty?
Yes, melting point is a physical property because melting is a physical change, and does not produce any new substances.
How does a substances melting point determine its state at room temperature?
If the melting point is under 20 oC the substance is a liquid.
Where is used?
It is used to seperate substances of different melting point
Do pure substances have a fixed boiling and melting point?
yes they have
What substances has the the most likely has highest melting point?
copper
What information do you need to tell if two substances are the same or different?
density , boiling point, melting point also mass & volume if you wanted to include those
What is the melting point of a battery?
Melting points are of pure substances, not of objects made out of many, many substances. Eg. A news paper or an aeroplain don't have a melting point. Neither do batteries. But be carefull in warming them up above 50oC !!
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
