The process of conversion of liquid into vapour by heating and the
vapour into liquid state again by cooling is called distillation.
Magnetic separation

The process of separating magnetic substances from non-magnetic
substances with the help of a magnet is called magnetic separation. If

there are pieces of magnetic substances such as iron, cobalt, nickel,
etc in the mixture, they are easily removed by attracting on a magnet.
This process is called magnetic separation.
