Question

A sample of gas has a volume of 10 ml at 2 atm. The pressure increases to 4 atm. What is the new volume?

Answer 1

The answer is 5 mL

Step-by-step explanation:

In order to find the new volume we use 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) \\`

We have

`V_2 = (10 * 2)/(4) = (20)/(4) \\`

We have the final answer as

5 mL

Hope this helps you
