Variables that affect Gas Pressure 1) Volume When the volume increases, the molecules are further apart, this decreases the pressure: less collisions When the volume decreases, the molecules are closer together - increases the pressure: more collisions Volume & pressure are inversely related: V α 1/P Boyle's Law 2) Temperature Increase of temp, the molecules move faster, this increases the pressure: more collisions Decrease of temp, the molecules move slower. This decreases the pressure: less collisions Volume & temp are directly related V α T Charles' Law 3) Changing the number of molecules in container If more molecules are added, there are more collisions - increase in pressure If molecules are taken out, there are less collisions - decrease pressure of molecules & pressure are directly related Combined Gas Law States that gas pressure & volume are inversely proportional, temp is directly proportional to pressure P1V1/T1 = P2V2/T2 Calculate the change of one of the final/new variables
