Are melting points of molecular substances higher than those of ionic substance?
Ionic substances have higher melting points.
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.
What is the melting temperature of titanium?
Titanium has a high melting point of 3135°F (1725°C). This melting point is approximately 400°F above the melting point of steel and approximately 2000°F above that of aluminum.
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 !!
Describe what a pure material or substance is?
These are substances that contain only one type of atoms/molecules. For example, diamond is a pure substance. Diamonds are made of strictly carbon atoms. Melting points and Boiling points of pure substances always remain constant !
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 is melamine's melting point?
melting point of approximately 354°C 669.2°F
What are some things that have melting points?
All substances have a melting point.Water, for example, has a melting point. It is simply the temperature at which a substance changes states to a liquid.
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.
Why do different substances require different amount of heat energy during melting?
due to different melting point...
