  Barometer
• For this matter, the pressure arises from the collision between gas molecules and the surface

  gas
• It is the ratio of force to the area on which the force is acted

  Pressure
• What law states that the pressure (P) exerted by the gas is inversely proportional to its volume (V)

  Boyle's Law
• P1V1=P2V2

  Boyle's Law

  Isotherm

  
• Jaques-Charles and Joseph Gay Lussac focused on the relationship between temperature and volume of a given amount of gas at a fixed temperature. This law is called _____

  Charle's Law
• For a given amount of fixed pressure, the volume of the gas is directly proportional to its absolute temperature. The plot shows the relationship between temperature and volume at a constant pressure called _____

  Isobar

  
• V1/T1 = V2/T2

  Charle's Law
• For a given amount of gas at a constant volume, the pressure is directly proportional to its absolute temperature. Just like temperature - volume plot, a temperature - pressure plot which is called ______ is also linear

  Isochore

  
• P=K^3T

  Charle's Law
• This law states that equal volumes of different gases are subjected to the same pressure and temperature have equal quantities of atoms or molecules

  Avogadro's Law
