Gas Laws

• Kinetic Molecular Theory 


  it says here that the gas molecules continuously travel in straight lines and only change their direction during collisions with the container wall and other molecules.
• Pressure 


  it is defined as the FORCE the gas exerts on a given area of the container.
• Volume 


  it is the THREE-DIMENSIONAL SPACE inside the container holding the gas.
• What is the SI unit for volume?

  cubic meter (m³)
• What is the more common and convenient unit for volume?

  liter (L)
• What is the standard unit for pressure?

  • Atmosphere (atm)
  • Millimeters of Mercury (mm Hg)
  • Pounds per square unit (psi)
• Temperature 


  it measures the HEAT, or HOW FAST the particles are moving.
• What is the absolute temperature when working with GASES?

  Kelvin
• What is the standard temperature?

  0⁰C 273k
• Celsius to Kelvin

  K= ⁰C + 273.15
• Kelvin to Celsius

  ⁰C = K - 273.15
• Amount (Moles)


  it is the amount of substances
• What is the SI unit for Amount of Substance?

  Mole (mol)
• One mole of a substance contains approximately 6.022 × 10²³ particles of the substance.
• What are the properties of gases?

  1. Pressure
  2. Temperature
  3. Volume
  4. Amount (moles)
• Boyle's Law 


  it describes the relationship between PRESSURE and VOLUME OF GASES.
• The Boyle's Law is named for?

  Robert Boyle
• The SAME AMOUNT of gas at a CONSTANT temperature, results in an inverse relationship.
• What is the formula for Boyle's Law?

  P1V1 = P2V2
• Boyle's Law Statement

  “The volume of a confined gas is inversely proportional to the pressure given that it's temperature is constant.”
• Charles Law 


  it is the relationship between VOLUME and TEMPERATURE at a constant PRESSURE.
• The Charles Law is named for?


  Jacques Charles
• Charles Law 


  In his experiment, he trapped a sample of gas in a cylinder with a movable piston in water bath at different temperatures.

  What Law is this?
• What is the formula for Charles Law?

  V1/T1 = V2/T2
• What is the formula for Charles Law in cross-multiplied form?

  V1T2 = V2T1
• Charles Law

  it says here that as the TEMPERATURE Increases, the VOLUME also increases because faster molecules collide harder and push each other farther apart. This results to Direct Relationship.
