Question

The pressure is changed from 500 kPa to 250 kPa. What would you expect the new volume to be if the initial volume is 200 mL?

Answer 1

The answer is 400 mL

Step-by-step explanation:

The new volume 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 are finding the new volume

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

So we have

`V_2 = (500000 * 200)/(250000) = (100000000)/(250000) = (10000)/(25) \\`

We have the final answer as

400 mL

Hope this helps you
