Energy
A thermal energy grade 7
| Question | Answer |
|---|---|
| In what direction does thermal energy flow naturally? | Thermal energy naturally moves to a substance with a higher temperature to a substance with it’s lower temperature. |
| What is the conduction and how is it caused? | Conduction is the transfer of thermal energy through a substance, or between substance in contact. |
| What is conduction caused by? | Conduction is caused by the collision of particles. |
| What is the 3 things that happen in cooking an egg in a fry pan of a example of a conduction? | The 3 are the energy from the burner gose through the pan to the egg. The particles from the pan collide with the particles in the egg, it is causing the egg from the particles to move faster. The faster it gose the temperature of the egg to rise. |
| What is the difference between a conductor and an insulator? | Conductor are designed to transfer energy easily and quickly. Two metals that serve as good as conductors to conduct energy from a hot burner to cold food are copper and aluminum |
