Combined Gas Laws: (Boyle, Charles, and Gay-Lussac's Laws combined)
Please click image below because I can't write the letters in subscript.
P₁ = Initial Pressure
V₁ = Initial Volume
T₁ = Initial absolute temperature
Pf = Final Pressure
Vf = Final Volume
Tf = Final absolute temperature
Absolute temperatures are measured in Kelvin, NOT Celsius or Farenheit. Also, do not write the degree symbol.
Example: 187 K, not 187⁰ K.
