HOT AND COLD CAN GRAPH

TEMPERATURE CHANGE FOR THE HOT CAN THE TOTAL TEMPERATURE CHANGE WAS 3.4 IT STARTED OUT AS 40˚C AND AFTER 17 MINUTES IT INCREASED TO 43.4˚C FOR THE COLD CAN THE TOTAL TEMPERATURE CHANGE WAS 30.2, IT STARTED OUT AS 40˚C AND AFTER 22 MINUTES IT DECREASED 9.8˚C

HOT CAN AND COLD CAN ENERGY TRANSFER FOR THE HOT CAN THE ENERGY TRANSFER WAS CONDUCTION AND RADIATION. IT WAS CONDUCTION BECAUSE WE HAD THE HEATED SOCK FILLED WITH RICE WRAPPED AROUND THE CAN, AND IT WAS RADIATION BECAUSE THE HEAT FROM THE MICROWAVED RICE MADE THE CAN 43.4˚C. FOR THE COLD CAN, THE ENERGY TRANSFER WAS CONVECTION AND CONDUCTION. IT WAS CONDUCTION BECAUSE WE HAD THE COLD FOIL WRAPPED AROUND THE CAN, AND IT WAS CONVECTION BECAUSE THE COLD AIR FROM THE SALT AND ICE WAS CIRCULATING THROUGH THE BAG.

COMPARISON TO CONTROLLED CAN HOT CAN THE CONTROLLED CANS TEMPERATURE DECREASED A LITTLE BIT TO ABOUT 37˚C AND THE HOT CAN WENT UP TO 43.4˚C SO THE HOT CAN EXPERIMENT WORKED WELL BECAUSE IT STAYED WARM. COLD CAN THE CONTROLLED CANS TEMPERATURE ONLY DECREASED ABOUT 3˚C AND THE COLD CAN WE DID DECREASED TO 30.1˚C AND ENDED AT 9.8˚C SO THE COLD CAN EXPERIMENT WORKED REALLY WELL

HOW WE CAN MODIFY OUR DEVICE HOT CAN ADD MORE RICE NO AIR IS LEAVING THE COVERED AREA MICROWAVE THE RICE LONGER PUT MORE SOCKS AROUND THE CAN USE FUZZY SOCKS COLD CAN WE CAN ADD MORE ICE SHAKE BAG LONGER ADD MORE SALT PLACE OUTSIDE WITH BAG OF SALT AND ICE

EXAMPLES IN REAL LIFE HOT CAN WHEN YOU HAVE AN INJURY MOST PEOPLE ICE THE INJURY, BUT ITS BEST TO USE HOT AND COLD SO IF YOU MICROWAVE A SOCK WITH RICE IN IT YOU USE IT TO HEAT YOUR INJURY. COLD CAN FOR THE COLD CAN WE USED SALT AND ICE TO MAKE A BAG COLD, AND WHEN PEOPLE MAKE ICE-CREAM THEY USE ICE AND SALT ALONG WITH OTHER MATERIALS BUT THE WAY IT GETS COLD IS THE ICE AND SALT

PICTURES OF HOT AND COLD CANS THE COLD AIR WAS USING CONVECTION BY CIRCULATING AROUND THE CLOSED BAG TO MAKE THE WATER COLD THE HEATED SOCK WAS USING CONDUCTION BY HAVING THE HOT SOCK WRAPPED AROUND THE CAN TO HEAT THE WATER
