  373K
• Volume


  The amount of space occupied by matter
• Pressure


  The amount of force applied per unit area
• K


  SI unit used to describe temperature
• 300K


  Equivalent to 27°C
• If the pressure of a gas is doubled at constant temperature


  The volume of the gas is halved
• Boyle's Law


  V₁P₁ = V₂P₂
• Charles' Law


  Volume and temperature are directly proportional for a gas at constant pressure
• Units of volume


  • L
  • mL
  • m³
  • cm³
• According to Boyle's Law, the volume of a gas is inversely proportional to its pressure at constant temperature
• According to Charles' Law, the volume of a gas increases as the temperature increases at constant pressure
• Torr is not a unit for describing the amount of pressure
• Which of the following quantities are directy proportional in Charle’s Law?

  • Volume and temperature
• He stated that the pressure of a gas is inversely proportional to its volume if temperature is kept constant

  • Robert Boyle
• If the temperature increases, the volume of a gas also increases at constant pressure
• which formula you must use to solve for the value of T2 or V2?


  V1/T1 = V2/T2
• STP stands for

  • Standard Pressure and Temperature
• What is the standard temperature of a gas?

  273K
• In the equation for Boyle’s Law, P1, stands for?

  Initial Pressure
