2/28 Notes – Gas Laws Review

 

  1. Gas Laws

            A.        Review

                        1.         Temperatures

                                    All temperatures must be in Kelvin

                                    Kelvin = °C + 273.15

                        2.         Volume

                                    All volumes need to be in Liters

                        3.         Pressure

                                    Can be in atm or kPa

                                    1 atm = 101.325 kPa

                        4.         Combined Gas Law

                                    P1V1 = P2V2

                                    T1         T2

                        5.         Ideal Gas Law

                                    PV = nRT

                                    P = pressure

                                    V = volume

                                    n = moles

                                    R = gas constant

                                                Use 0.0821 if pressure is in atm

                                                Use 8.314 if pressure is in kPa

                                    T = temperature
