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:

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
