WHAT HEAT CAN DO
Materials:
- electric burner
- string
- piece of cardboard
- copper and iron wire
- ammeter
- iron stand with clamp
Diagram:
Pictures:
Results:
Based on our observation, in the set up A which is the paper turbine set up, the spiral cardboard moved in a spiral motion due to heat. In set up B, we observed that the iron and copper wire became hot and the ammeter repelled.
Discussions:
The energy that take place as the paper turbine starts to move is called mechanical energy. Furthermore, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.
Conclusion:
When heat passes from hot to cold objects molecules will move faster when they pass to hot objects and moves slowly to cold objects.
Heat is energy and the cold objects steals the heat from the hot object. This will occur until the temperature of both objects becomes equal. At this point there is no longer any flow of heat/energy between them.
If you pick up a cold object, the reason it feels cold is due to the heat it steals from your hand.
