Can someone answer this grade 9 question for me, please?
'Explain what happens to the substances during the process of distillation in terms of intermolecular forces of attraction.'

- Towards the start of the distillation process, a liquid is boiled and evaporates to become a gas.
- As you increase the temperature, the kinetic energy of the liquid particles will increase (they move faster).
- The intermolecular forces weaken between liquid particles until the liquid particles break free from the stronger intermolecular bonds of the liquid state.
- The liquid has turned into a gas, with intermolecular forces which are so weak that gas particles move about randomly.
- The gas then condenses to form a liquid in the Liebig condenser.
- The temperature of the gas decreases, so the kinetic energy of the gas particles will decrease (they move slower).
- The intermolecular forces will strengthen between gaseous particles, and the particles will get closer together until they become liquid.
- The gas has turned into a liquid, so the intermolecular forces have become stronger, holding particles together although not in a rigid formation.
