Question

a sample of gas X occupies 10 m^3 at a pressure of 120 kPa.if the volume of the sample is compressed to 3m^3 ,what is the new pressure of the gas?​

Answer 1

Answer:

400 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're finding the new pressure

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

120 kPa = 120,000 Pa

We have

$P_2 = \frac{120000 \times 10}{3} = \frac{1200000}{3} \\ = 400000$

We have the final answer as

400,000 Pa = 400 kPa

Hope this helps you
