Question
(i) Cold water flows through the condenser.
On the diagram, use arrows to show where the water should flow in and where it should flow out.
(i) Explain why a condenser is used.
Answer
A condenser is used to cool hot vapors from the evaporator and convert them back into a liquid form. The cold water flows in through the condenser and out after it has cooled the vapors. The arrows should show the water flowing in at the top and out at the bottom.
