### 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.

*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.
