Differences need to be listed for Evaporation and Boiling. 1 Element X can undergo the following physical changes. (a) (i) Give the scientific name for each of the numbered physical changes. (ii) Explain why the changes shown are physical changes. (iii) One difference between boiling and evaporation is the rate at which the processes occur. State one other difference between boiling and evaporation. (b) Describe the separation, arrangement and motion of particles of element X in the solid state (c) Element X is a Group I metal. It burns in air to form an oxide X2O Write a chemical equation for this reaction.
