Law names

100

What law relates volume and temperature 

Charles Law

200

Which law relates temperature and pressure

Gay Lussac's Law

300

Which law relates temperature, volume, and pressure

Combined gas law 

400

Which law has a temperature, pressure, volume, constant, and mass as variables. 

Ideal gas law 

500

Which law relates volume and pressure? 

Boyle's law

P₁V₁ = P₂V₂ 

Relationships

100

How are pressure and volume related?

Inversely related

200

As temperature increases, what will happen to volume?

Volume will increase

300

What two laws have a direct relationship? What does this mean?

Charles's Law & Gay-Lussac's Law. If one variable increases than the other also increases and vice versa.

400

How does a temperature increase relate to kinetic energy?

An increase in temperature causes an increase in kinetic energy (particles move faster).
