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.
Why does hydrogen bonding raise the melting and boiling point of water?
waters boiling point is 100 degree celcius
How many degrees are there between the melting point of ice and boiling point of water?
The ice point and steam point that you refer to are called the boiling and freezing point. Each substance has a different boiling and freezing point, though for water it is 0 degrees Celsius is freezing and 100 degrees Celsius is boiling. Or if you use Fahrenheit, it is 32 degrees Fahrenheit for freezing and 212 degrees Fahrenheit for boiling. So depending on what system of measurement you use for temperature, the number of degrees separating the boiling and freezing points of water can be 100 degrees for Celsius or 180 degrees for Fahrenheit.

How does a substance's boiling point or melting point determine its state at room temperature?
If its still a solid at room temperature then to melt it would have to be at a higher temperature than 20 degrees. If its still a solid at room temperature then to melt it would have to be at a higher temperature than 20 degrees.

Short difference between melting and boiling point?
Boiling point is the temperature at which a liquid is in equilibrium with the gas phase of the same liquid. Melting point is the temperature at which a solid becomes a liquid (i.e. the point at which a solid and liquid of the same substance will be in equilibrium)
Compare boiling and freezing point?
for example ....water:freezing point: liquid freezes to ice boiling point: liquid boils and turns into vapor melting point: ice melts to liquid
