Notes #2: Boyles & Charles Laws WCHS Chemistry YOU NEED A CALCULATOR!
Air Bubbles Dolphins Syringe
BOYLE’S LAW = The volume of a gas increases as the external pressure decreases Ex: Bubbles rising in a pool Ex: A syringe
P____ means V _____ & P____ means V _____ BOYLE’S LAW P____ means V _____ & P____ means V _____ External External Boyle’s Equation: P1V1 = P2V2 Volume Units = Liters (L)! Be careful of mL! Pressure Units = atmospheres (atm) or Torr Atmospheres = Torr 760
Hot Air Balloon
CHARLES’ LAW = As the temperature of a gas increases, the volume increases (and vise versa) Ex: Inflating a hot air balloon Ex: Balloon in a freezer
CHARLES’ LAW T____ means V _____ & T____ means V _____ Charles’ Equation: V1 = V2 T1 T2 Volume Units = Liters (L)! Be careful of mL! Temperature Units = Kelvin (K) Kelvin = oC + 273
