Like solids, liquids dont easily compress
or expand.

Gases
ozone
Tend to occupy all the space available to them.
Heat causes molecules to speed up and spread out.

Terms
Temperature Pressure Boyles
Law Charless Law
Measurement of average energy of motion of
particles of substance
Force of outward push divided by the area of the
walls of the container PF/A
When pressure of a gas is increased at constant
temperature, the volume of the gas decreases.
When the pressure is decreased, the volume
increases.
When the temperature of a gas is increased at
constant pressure, its volume increases. When
the temperature of a gas is decreased at constant
pressure, its volume decreases.
9
Notes
Volume is dependent upon temperature and pressure
10
Measuring Gases
Volume is dependent upon the size of the
container. Temperature Pressure Gasses travel
from higher pressure to lower pressure

What happens when the gas is compressed?
Pressure Increases
Volume Decreases

Boyles Law
When pressure of a gas is increased at constant
temperature, the volume of the gas decreases.
When the pressure is decreased, the volume
increases.

Bernoullis Principle
A stream of fast moving fluid exerts less
pressure than the surrounding fluid.

Relating Pressure Temperature
Remember that Pf/a
Temperature is just the measure of the average
speed of the moving Particles of the gas.

Charless Law
When the temperature of a gas is increased at
constant pressure, its volume increases. When
the temperature of a gas is decreased at constant
pressure, its volume decreases.

Graph Directly Proportional Vary
Inversely
A diagram that tells how two variables,or
factors, are related.
When a graph of two variables is a straight line
passing through the (0,0) point
When a graph of two measurements forms a
non-linear curve away from the (0,0) point
