By: Rebekah Greenspan and Lexi Smith CAN CHALLENGE
1.Build the insulator 2.Pour hot water into the can and seal the top with your lid 3.Stick the thermometer through the lid into the can so it touches the bottom of the can. 4.Place the insulator in a plastic bag, then, the whole thing into a bucket of ice water 5.Monitor the temperature for 20 minutes. 6.Calculate the loss of temperature of your insulator WHAT IS THE CAN CHALLENGE?
OUR OBJECTIVE Our objective was to apply our knowledge of heat and energy transfer to evaluate different materials and construct an insulator for a regular sized soda can filled with hot water.
WHAT ARE INSULATORS? Insulators are materials whose atoms have tightly bound electrons. These atoms are not free to roam around and transfer energy to other atoms.
WHAT IS HEAT Heat is thermal energy moving from a warmer object to a cooler one and thermal energy is the total energy in an objects particles
Radiation: Convection: Conduction: TYPES OF HEAT TRANSFER
