 Figure 3 shows two aluminium containers, A and B placed on a wooded table. A and B have equal volumes of hot water initially at the same temperature.

answers

• The rate of cooling depends on the rate of evaporationRate of evaporation depends on the surface area
• Surface area A, < surface area B for evaporation
