It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance.
Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
The temperature point to which you refer is known as the 'triple point' of water. This is at 273.16 K, or .01 deg Celsius. Other liquids and gases also have a triple point. In the case of water, this is the temperature at which its three phases; solid, liquid, and gas; may co-exist. The triple point of water is only one of a number of temperatures that are used to produce a wide and useful series of temperature scales.
Many substances have different melting and boiling points, thus one can use their melting and boiling points to identify them.
because it freezes
the boiling point of lemonade is 112 C
Yes it can. I'm not sure if you need any other examples but color and melting/boiling point can as well.
The melting point is between 3652 and 3697 degrees C. The boiling point is 4200 degrees C.
Melting requires energy input or absorption because liquid water has more energy than solid water.
The melting point of tantalum is 3 017 0C.The boiling point of tantalum is 5 458 0C (this is a very high boiling point).
intermolecular forces are hard to overcome...apex
Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
Melting and boiling points are different for each compound or element.
Flexibility, Smell, Odor, Boiling Point, Melting Point, Texture, Color (there's seven for you)
Each pure substance has its own unique melting and boiling point.
yes they have
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.
Adding impurities lowers the melting point and raises the boiling point.
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
