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

400 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're finding the new pressure

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

120 kPa = 120,000 Pa

We have

`P_2 = (120000 * 10)/(3) = (1200000)/(3) \\ = 400000`

We have the final answer as

400,000 Pa = 400 kPa

Hope this helps you
