Slide2:
3 Thermometer
3 Beakers
Insulation
Water
Cotton
Slide3:
Place insulation in one can, water in the other and cotton in the last one
Place the three cans in a hot water bath
Record the temperature inside each can
Record the temperature of the water in the hot water bath
Continue recording the temperature every 30 seconds for 3 minutes
Slide5:
The insulation
The water
The cotton
Answer: The can with the water got the hottest. (B)
Slide6:
The insulation
The water
The cotton
Answer: The can that the temp changed the least was the can with the water in it. (B)
Slide7:
The insulation
The water
The cotton
Answer: Cotton is the best insulator because it slows the heat transfer.
Slide8:
Cotton
Insulator
Water
Slide9:
The experiment is demonstrating heat transfer because this experiment uses conduction. Conduction is heat transfer through a solid or liquid as a result of vibrating of loose electrons- direct contact between the two substances.
Slide10:
The methods of heat transfer are listed below.
Radiation
Convection
Conduction
heat transfer:
heat transfer Heat transfer is occurring because the heat is going through the can through the insulators and to the thermometer.
Difference in heat transfer in the different materials. :
Difference in heat transfer in the different materials. A good insulator is a bad conductor of heat , a bad insulator is a good conductor.
Cotton is the best insulator so it is the worst conductor. Insulator is the second to the best insulator. Water is the worst insulator and usually the worst conductor, but in this case it is the best conductor.
