Answer: The oxygen gas has a pressure of 4 atm if my volume decreases to 1 L.
Explanation:
Given:
= 2 L,
= 2 atm
= 1 L,
= ?
Formula used to calculate the new pressure is as follows.
![P_{1}V_{1} = P_{2}V_{2}](https://tex.z-dn.net/?f=P_%7B1%7DV_%7B1%7D%20%3D%20P_%7B2%7DV_%7B2%7D)
Substitute the values into above formula as follows.
![P_{1}V_{1} = P_{2}V_{2}\\2 atm \times 2 L = P_{2} \times 1 L\\P_{2} = 4 atm](https://tex.z-dn.net/?f=P_%7B1%7DV_%7B1%7D%20%3D%20P_%7B2%7DV_%7B2%7D%5C%5C2%20atm%20%5Ctimes%202%20L%20%3D%20P_%7B2%7D%20%5Ctimes%201%20L%5C%5CP_%7B2%7D%20%3D%204%20atm)
Thus, we can conclude that the oxygen gas has a pressure of 4 atm if my volume decreases to 1 L.
