Question

Part A: A sample of ideal gas at room temperature occupies a volume of 16.0 L at a pressure of 692 torr. If the pressure changes to 3460 torr, with no change in the temperature or moles of gas , what is the new volume, V2? Express the volume numerically in liters.
Part B: If the volume of the original sample in Part A (P1= 692 torr, V1= 16.0 L) changes to 51.0 L , without a change in the temperature or moles of gas molecules, what is the new pressure, P2? Pressure and Volume Part A For a certain amount of gas at constant temperature, the pressure and volume have an inverse relationship (Figure This is called Boyle's law A sample of ideal gas at room temperature occupies a volume of 16 0 L at a pressure of 692 torr If the pressure changes to 3460 torr, with no change in the temperature or moles of gas, what is the new volume, V?

Explanation / Answer

Part A :

volume V1 = 16.0 L

pressure P1 = 692 torr

pressure P2 = 3460 torr

volume V2 = ??

from boyle's law :

P1 V1 = P2 V2

692 x 16 = 3460 x V2

V2 = 3.2 L

volume = 3.20 L

Part B)

P1= 692 torr

V1= 16.0 L

V2 = 51.0 L

P1 V1 = P2 V2

692 x 16 = P2 x 51

P2 = 217 torr

pressure = 217 torr
