Melting and Boiling Points

Melting and Boiling Points The melting point is the temperature at solid which a substance changes from a. . . liquid to a. . . The boiling point is the temperature at liquid which a substance changes from a. . . gas to a. . . 0 100 °C. Water melts at. . . °C and boils at. . . .

Material Melting Point (o. C) Aluminium 660 Helium -270 Bromine -7 Iron 1537 Water 0 Ethanol -117 Oxygen -218 Nitrogen -210 Material Boiling Point (o. C) Aluminium 2467 Helium -269 Bromine 59 Iron 2927 Water 100 Ethanol 79 Oxygen -183 Nitrogen -196

Separation Techniques A Mixture is formed from different substances that are not chemically joined together. Some mixtures are insoluble eg Sand Water Some mixtures are soluble eg Salt and Water
