Large crystals of pure substances can be formed from their solutions. This process is called crystallisation. It is an example of a physical change. Take a cup full of water in a beaker and add a few drops of dilute sulphuric acid. Heat the water when it starts boiling add copper sulphate slowly while stirring continuously. continue adding copper sulfate powder till no more powder can be dissolved. Filter the solution. Allow it to cool. Do not disturb it cooling. Look at the solution after sometime.
