1 Fig. 1.1 shows three containers painted black, white and silver, filled with tap water, exposed to direct sunlight. Jason wanted to find out whether colour of the container would affect the amount of heat energy gained by the water. Jason measured the initial temperature and final temperature of the water in each container after 30 minutes. black container white container silver container For this investigation, state the (a) aim of this experiment.
