Physics 1 - 1.4

HideShow resource information
Conduction occurs mainly in what, solids; liquids or gases?
Solids.
1 of 9
Most liquids and all gases are poor or good conductors?
Poor.
2 of 9
If one end of a solid is heated, what happens to the particles?
The particles at that end gain kinetic energy and vibrate more. This energy is passed to neighbouring particles and in this way the energy is transferred through the solid.
3 of 9
The process described in question 3 occurs in what?
Metals.
4 of 9
When metals are heated, their free electrons gain kinetic energy and move through the metal, transferring energy by colliding with other particles. What does this mean?
Metals are good conductors.
5 of 9
Poor conductors are called what?
Insulators.
6 of 9
Name two good insulators.
Wool and fibreglass.
7 of 9
Why are wool and fibreglass good insulators?
They contain trapped air.
8 of 9
What are they key words for this topic?
Conduction, Conductor, Free Electron, Insulator.
