Question

A gas has a volume of 50mL at a pressure of 2 atm. Increase the volume to 200mL, and the temperature remains constant. What is the new pressure?

Answer 1

The answer is 0.5 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 are finding the new pressure we have

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

We have

`P_2 = (50 * 2)/(200) = (100)/(200) = (1)/(2) \\`

We have the final answer as

0.5 atm

Hope this helps you
