# Question #d400a

##### 1 Answer

#### Explanation:

We can solve this problem using the *pressure*- *volume* relationship of gases, illustrated by **Boyle's law**:

We can see that pressure and volume for gases are *inversely proportional*, indicating that as one increases, the other must decrease (assuming constant temperature). Since the volume *decreased*, we can expect an *increase* in the pressure of the gas.

To keep calculations consistent, let's convert the units

Now that we have our necessary variables, let's rearrange the Boyle's law equation to solve for the final pressure,

Now, plugging in known variables, we have

The units for pressure above, *pascal* (symbol

Thus, the pressure can also be reported as

If you want another unit of pressure, a more common one when dealing with gases, we can convert this to *atmospheres* using the conversion factor
