gases pt. 2: gas laws

• boyle's law


  at constant temperature and amount of sample gas, the volume occupied by a fixed amount of gas is inversely proportional to the external pressure; increasing volume decreases pressure
• volume and pressure have a ______ relationship

  inverse
• mathematical relationship between volume and pressure

  V = 1/P
• mathematical interpretation of Boyle's Law

  P1V1 = P2V2
• Charles' Law


  at constant pressure and amount of gas, the volume occupied by a fixed amount of gas is directly proportional to its absolute (Kelvin) temperature; increasing temperature increases volume
• Kelvin is an _____ scale; the smallest value is ___

  absolute, 0
• mathematical interpretation of Charles' Law

  V1/T1 = V2/T2
• ideal gas law


  PV=nRT
• combined gas law

  P1V1/n1T1 = P2V2/n2T2
• The _____ is used when there is a single subset of conditions (P, V, n, T).

  ideal gas law
• The _____ is used when there are 2 subsets of conditions.

  combined gas law
