Aim: To investigate on the impact of size and shape on the rate of cooling Materials/Equipment: • 3 Plastic containers • thermometer • boiling water • stopwatch • measuring cylinder.

Hypothesis: We believe that the larger rectangular container will cool down faster, than any other container. The rectangular container will lose all the heat because of its wider space and open area, the heat would escape quicker. And all the other containers will lose less heat because if its size and shape.

Flow Chart •The equipment was set up

•The water was poured into the container •The thermometer was put in and the temperature was recorded •Every 5 minutes for 15 minutes the temperature was checked. •The loss of heat was then calculated
