P2.1 - Energy Transfer By Conduction (FMock?)

Question 1

How do you test different materials as conductors (rods)?

Answer 1

Get three rods of different materials and put some wax on one end. Heat the other end of all 3 rods with 1 bunsen burner and see which ones wax melts first

Question 2

What is thermal conductivity?

Answer 2

The energy per second a material can transfer by conduction

Question 3

Give three things that affect the energy transfer per second through a lager of material?

Answer 3

• The temperature difference across it
• The thickness of it
• The thermal conductivity of it

Question 4

What is conduction?

Answer 4

The process by which vibrating particles transfer energy to neighbouring particles

Question 5

Explain the process of conduction?

Answer 5

The particles in the part of the object being heated vibrate more and collide with each other. These collisions transfer kinetic energy between them.
