Chapter 4-3, 4-4 Properties of Gases Flashcards
Explain Dalton’s Law
the pressure exhibited by a mixture of pressures is equal to the sum of the individual pressure of each gas that makes up the mixture
Explain Boyle’s Law
the volume of the gas is inversely proportional to the pressure of that gas as long as the temperature and number of mols of gases remain unchanged
What is the formula for Dalton’s Law?
Ptotal = P1+P2+…Pn
What is the formula for Boyle’s Law?
What do the formula components stand for?
PiVi = PfVf
Pi = initial pressure
Pf = final pressure
Vi = Initial volume
Vf = final volume
Explain Gay-Lussac’s Law
pressure of the gas is directly proportional to the absolute temperature, which is given in Kelvin if volume and number of mol in gases are unchanged
What is the formula for Gay-Lussac’s Law?
Pi/Ti = Pf/Tf
Pi = initial pressure
Pf = final pressure
Ti = initial temperature
Tf = final temperature
Explain the Charles’ Law
The volume of a gas is directly proportional to the absolutely temperature provided the pressure and number of mols are unchanged.
if the volume increases, the temperature also increases and vice versa
What is the Charles’ Law equation
Vi/Ti = Vf/Tf
Vi = initial volume
Vf = final volume
Ti = initial temperature
Tf = final temperature
Explain the combined gas law
the gas sample is subject to changes from pressure, volume, and temperature all at the same time
What is the combined gas law formula?
Pi x Vi/Ti = Pf x Vf/Tf
What temperature must all gases be calculated in?
Kelvin
What is the conversion for absolute temperature?
1 Calorie = 1,000 calories
