Question 1: A sample of ideal gas at room temperature occupies a volume of 34.0L at a pressure of 722 torr. If the pressure changes to 3610 torr, with no change in the temperature or moles of gas, what is the new volume, V2?
Question 2: If the volume of the original sample in Part A (P = 722 torr, V1= 34.0 L) changes to 57.0 L, without a change in the temperature or moles of gas molecules, what is the new pressure, P2?
