Density
mass/volume
1 of 9
Pressure
force/area
2 of 9
Pressure Difference
height x density x gravity
3 of 9
Pressure acts equally in all directions
When in a gas or liquid
4 of 9
Molecules in a gas
have random motion and exert a force putting pressure on the walls of the container
5 of 9
Absolute Zero
-273 degrees because the particles have completely stopped moving
6 of 9
Increase in temperature
leads to an increase in the average speed of gas molecules
7 of 9
Pressure and Volume of a fixed mass of gas at a constant temperature
p1v1 = p2v2
8 of 9
