How do Gases Change with Different Conditions?
This post will go through the basic gas laws that describe the relationship between the volume of a gas and temperature, pressure and the number of moles for Prelim Chemistry.
Topic: Gas Laws
- Conduct investigations and solve problems to determine the relationship between the Ideal Gas Law and:
- Gay-Lussac’s Law (temperature)
- Boyle’s Law
- Charles’ Law
- Avogadro’s Law
The Gas Laws
There are four main gas laws and the combined gas law. The laws and the relationships they describe (assuming the other factors are constant) are:
Gay Lussac’s Law -> pressure and temperature (volume and moles constant)
P1/T1 = P2/T2
Boyle’s Law -> pressure and volume (temperature and moles constant)
P1V1 = P2V2
Charle’s Law -> volume and temperature (pressure and moles constant)
V1/T1 = V2/T2
Avogadro’s Law -> volume and moles (pressure and temperature constant)
V1/n1 = V2/n2
Combined Gas Law
(P1V1)/T1 = (P2V2)/T2
Note that these are simplified descriptions of the gas laws and it is advised you go through them in a little more depth.
This video below will better describe gas laws which will help you with understanding how to use them.
