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

Answer:

The answer is

112.912 kPa

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

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

404.6 kPa = 404600 Pa

From the question we have

$P_2 = \frac{404600 \times 12}{43} = \frac{4855200}{43} \\ = 112911.6279... \\ = 112912$

We have the final answer as

112.912 kPa

Hope this helps you
