Question

I have oxygen gas at 2 L and 2 atm. At what pressure is the oxygen gas if my volume decreases to 1 L?

Answer 1

Answer: The oxygen gas has a pressure of 4 atm if my volume decreases to 1 L.

Step-by-step explanation:

Given:
`V_(1)` = 2 L,
`P_(1)` = 2 atm

`V_(2)` = 1 L,
`P_(2)` = ?

Formula used to calculate the new pressure is as follows.

`P_(1)V_(1) = P_(2)V_(2)`

Substitute the values into above formula as follows.

`P_(1)V_(1) = P_(2)V_(2)\\2 atm * 2 L = P_(2) * 1 L\\P_(2) = 4 atm`

Thus, we can conclude that the oxygen gas has a pressure of 4 atm if my volume decreases to 1 L.
