Question

A gas has a volume of 25 ml, at a pressure of 1 atmosphere (1 atm). Increase the volume to 125 ml and the temperature remains constant. What is the new pressure? please help

Answer 1

0.2 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we're finding the new pressure

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

We have

$P_2 = \frac{25 \times 1}{125} = \frac{25}{125} = \frac{1}{5} = 0.2$

We have the final answer as

0.2 atm

Hope this helps you
