Hint: We know that the melting point of ice is 0oC. So we have to convert temperature from Celsius to Kelvin scale. For this, we have to add 273 to the value in Celsius. Therefore, we can say the melting point of ice in the Kelvin scale is 273K. Complete step by step solution: We must know that the melting point is the temperature at which a substance changes its phase from solid to liquid without an increase in temperature. We know that the melting point of ice is 0oC. In order to convert the temperature from Celsius to Kelvin scale, we add 273. Therefore, the melting point of ice in Kelvin= 0 + 273 = 273 K Note: 1. The melting point of a compound is affected by force of attraction between the molecules. Stronger intermolecular interactions between the molecules, higher will be the melting points. For example the ionic compounds usually exhibit high melting points because the ion-ion interactions are very strong. 2. The chemical element which has the lowest melting point is Helium and the element with the highest melting point is carbon. 3. We must know the basic difference between melting and boiling point. If at specific temperature, material changes from a liquid to a gas (boils) it is known as a boiling point. Also at specific temperature, material changes from a solid to a liquid (melts) it is known as melting point. 4. Keep in mind that a material's melting point is the same as its freezing point.
