Question

The gas in a 350 mL balloon has a pressure of 0.85 atm. If the temperature remains constant, what will be the pressure of the gas in the balloon if the volume increases to 450 mL?

Answer 1

0.66 atm

Step-by-step explanation:

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

`P_1V_1 = P_2V_2`

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new pressure

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

We have

`P_2 = (350 * 0.85)/(450) = (297.5)/(450) \\ = 0.661111...`

We have the final answer as

0.66 atm

Hope this helps you
