Question 3

Process of simple distillation

Answer 3

• evaporate liquid by heating
• condense vapour back to liquid by cooling

Question 4

Describe process of fractional distillation

Answer 4

• heat mixture so that liquid with lower boiling point evaporate more easily
• mixture of vapours hit fractionating column they condense and drop back into flask where liquids evaporate again
• hit condenser and repeat
