A) A sample of ideal gas at room temperature occupies a volume of 13.0 L at a pressure of 562 torr . If the pressure changes to 2810 torr , with no change in the temperature or moles of gas, what is the new volume, V2?
B) If the volume of the original sample in Part A (P1 = 562 torr , V1 = 13.0 L ) changes to 69.0 L , without a change in the temperature or moles of gas molecules, what is the new pressure, P2?
