Question

Pressure and Volume Part A For a certain amount of gas at constant temperature, the pressure and volume have an inverse relationship Figure 1). This is called Boyle's law A sample of ideal gas at room temperature occupies a volume of 11.0 L at a pressure of 402 torr. If the pressure changes to 2010 torr, with no change in the temperature or moles of gas what is the new volume, V2? Express your answer with the appropriate units Hints v2_ Value Units Figure 1 of 1 Submit My Answers Give Up Part B If the volume of the original sample in Part A (P-402 torr , Vi = 11.0 L ) changes to 75.0 L without a change in the temperature or moles of gas molecules, what is the new pressure, P2?

Explanation / Answer

part A)

volume V1 = 11.0 L

pressure P1 = 402 torr

pressure P2 = 2010 torr

volume V2 = ??

P1 V1 = P2 V2

402 x 11 = 2010 x V2

V2 = 2.20

volume V2 = 2.20 L

part B)

volume V1 = 11.0 L

pressure P1 = 402 torr

volume V2 = 75.0 L

402 x 11 = 75 x P2

P2 = 58.96 torr

pressure P2 = 59 torr
