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

Answer:

The answer is 0.5 atm

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

$P_2 = \frac{P_1V_1}{V_2}$

We have

$P_2 = \frac{50 \times 2}{200} = \frac{100}{200} = \frac{1}{2}$

We have the final answer as

0.5 atm
