Thermal Energy Transfer In Cans Of Water Created By Mason P & Anthony G The Hot System So, uh, the hot system is comprised of duct tape, bubble wrap, foam, copper wire coil, and a soup can. Inside the soup can there is microwaved rice which heats up the soda can by conduction then the can heats up the water by conduction as well. The Cold System So, the cold system is comprised of a 6v battery which carries a current of 1.5a to the fan which uses convection to take thermal energy away from the fins of the heat sink which uses conduction to cool the can which in turn cools the water using conduction.

This means our idea for keeping the hot can warm worked. The cold can, however, went down 14.9C from 41C to 26.1C, which if also compared to the controlled can, youkan say that it worked. Real World Examples So we could use our hot system to heat soup in a can that you want warm. So you could use our cold system to keep a can of actual soda cold on a hot day when you want refreshments. Modifications For the cold system we could have used a bigger battery to make the fan spin faster and cool off the water more. For the hot system we could have heated the rice more and used more insulation so that the thermal energy could not escape.
