One molecule of the ground nut oil contains 56 carbon atoms, 104 hydrogen atoms and 6 oxygen atoms. The wick is made of cotton, which are strands of fibres. The cotton wick we dip in the groundnut oil in the lamp absorbs the oil due to the force of adhesion

The oil molecules stay together in the lamp because of the forces of cohesion When we light the oil lamp, the oil is continuously supplied to the wick by the action of capillarity.
