Physics 1A - Energy: Kinetic Theory and Conduction.

HideShow resource information
Name three states of matter.
Solid, liquid, gas.
1 of 11
Solids have strong forces of...
...attraction
2 of 11
What does the strong force of attraction in a solid do?
Holds the particles close together.
3 of 11
Liquids have a weak force...
...of attraction.
4 of 11
What does the weak force of attraction in a liquid do?
Makes them move close together but able to move past each other.
5 of 11
There are almost no forces of attraction between the particles. What state of matter is this?
Gas.
6 of 11
Gas particles are free to move how?
In any direction and at high speeds.
7 of 11
What happens when you heat something?
The particles get more energy and move or vibrate faster.
8 of 11
What does heating vibrating particles cause?
Causes solids to melt and liquids to boil.
9 of 11
Define "Conduction of Heat"
Conduction of heat is where vibrating particles pass on their energy to the particles next to them.
10 of 11
Why do metals conduct well?
Because they have electrons that are free to move inside the metal.
