# If #9 L# of a gas at room temperature exerts a pressure of #15 kPa# on its container, what pressure will the gas exert if the container's volume changes to #4 L#?

##### 1 Answer

#### Explanation:

From the information given for this question, we can see that this kind of situation is involving **Boyle's Law.**

**Boyle's Law** states that the **pressure** of a **fixed mass** of gas at a **constant temperature** is **inversely proportional** to its **volume** .

In which from the definition, the equation is derived as;

When there are **two situations** , given **initial** and **final value** of both pressure and volume, the equation is derived as;

From the information given in this question;
