The behavior of gases

THe three states of matter

• Almost all things can exist as only one
• Either a solid, liquid, or gases 
• H2O  or water is an example that can be all 3
• H2O can be frozen into a solid
• Boiled into a gases steam and through condensation turned into a liquid

Kinetic Molar theory

• According to this all matter is made of tiny particles 
• That are in constant, random, stright-line motion
• The motion is always interupted by the collison of particales
• The speed of the motion is dependent on the temperatuer  

CHARACTERISTICS of gases

• The volume of gases is nearly all empty space
• Particles are able to move freely 
• They are easily compressible because of the empty space
• This allows particles to be pushed together
• Gases are both expandable and compressible

Converting Between Pressures
1 atm=760 mm Hg=101.3 kPa

Converting between pressures ex.

• Convert 1104 torr to atm
• 1104 torr * 1 atm/760=
• 114/760=
• 1.45263....
• 1.453 (rounded)

gas law Formulas

• P1V1=P2V2 Boyle's law
• V1/T1=V2/T2 Charles' law
• P1/T1=P2/T2 Gay-Lussac's Law
• P1*V1/T1=P2*V2/T2 Combined gas law
• PV=nRT Ideal gas law
