Question

A gas at constant temperature has a pressure of 404.6 kPa with a volume of 12 ml. If the volume changes to 43ml, what is the new pressure

Answer 1

The answer is

112.912 kPa

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`

Since we are finding the new pressure

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

404.6 kPa = 404600 Pa

From the question we have

`P_2 = (404600 * 12)/(43) = (4855200)/(43) \\ = 112911.6279... \\ = 112912`

We have the final answer as

112.912 kPa

Hope this helps you
