Ch.3, Sec.2 Behavior of Gases
- gas particles can change because of temperature
pressure

• temperature a measure of how hot or cold
  something is specifically, a measure of
  the movement of particles

- particles move faster when temperature rises
create more expansion
- particles move slower when temperature
decreases create less expansion

• volume a measure of the size of a body or
  region in a 3D space

- volumes of gases can be manipulated quite
easily because of compression

Ch.3, Sec.2 Behavior of Gases
- balloons with gases can be shaped, but try it
with water they break apart!

• pressure the amount of force exerted per unit
  area of a surface

- the more particles hitting the inside surface
of an object, the greater the force of pressure
(think of the difference between a basketball a
beach ball)

Ch.3, Sec.2 Behavior of Gases

• Gas Behavior Laws

- temperature, pressure, and volume of gases are
linked, so we describe them with 2 laws

• Boyles Law the volume of a gas is inversely
  proportional to the pressure of a gas when
  temperature is constant. (pg.72)

Ch.3, Sec.2 Behavior of Gases

• Charless Law the volume of a gas is directly
  proportional to the temperature of a gas when
  pressure is constant. (pg.73)
