# What is the relationship between pressure and volume in Boyle's Law?

##### 2 Answers

At a constant temperature of a gas, the following rule (Boyle's Law) applies:

Where

#### Answer:

Pressure and volume have an indirect relationship

#### Explanation:

According to the Combined Gas Law:

This is just the general formula, and Boyle's Law is derived from it. Boyle's Law says that temperature is constant. So, we can remove temperature from the equation, making our new equation:

If we were to graph pressure on the y-axis and volume on the x-axis, we would see an indirect relationship occur.

To be honest, the way I always remember it is this:

Since we are not dealing with temperature here, there is an indirect relationship.
