Question

A gas expands from 2.5 L to 8.6 L at a constant temperature. If the initial pressure is 1.6 atm, what is the final pressure?

Answer 1

0.47 atm

Step-by-step explanation:

The final pressure can be found by using the formula for Boyle's law which is

`P_1V_1 = P_2V_2`

Since we are finding the new pressure

`P_2 = (P_1V_1)/(V_2) \\`

From the question we have

`P_2 = (2.5 * 1.6)/(8.6) = (4)/(8.6) \\ = 0.465116...`

We have the final answer as

0.47 atm

Hope this helps you
