Question
A glass vessel (rigid, but limited in the pressure of gas it can hold) contains 28g nitrogen gas. Assuming ideal gas behavior, circle the letter(s) of the process(s) listed below that would double the pressure exerted on the walls of the vessel. (a) Adding enough Hg(l) at the same temperature of the nitrogen to fill one half the container. (b) Raising the temperature of the container from 30 degree C to 60 degree C (c) Raising the temperature of the container from -73 degree C to 127 degree C (d) Adding 28 g nitrogen pas at the same temperature. A cylinder holds Ar gas at a pressure of 800 torr. Some Ar is removed with a syringe and this removed Ar occupies a volume of 60 mL and exerts a pressure of 750 torr in that syringe. The pressure of the Ar gas remaining in the cylinder drops to 560 torr, What is the volume of the cylinder? (Assume the temperature remains constant).Explanation / Answer
Can this be solved for qualitatively using the “initial-final” containing version ofthe ideal gas law?
Yes------------answer
===================================================
glass vessel contains 28 g nitrogen gas. Assuming ideal behavior, which of the following processes listed below would double the pressure exerted on the walls of the vessel?
Processes a, c, and d will all result in a doubling of the pressure. ------------answer
Process a has the effect of halving the volume, which would double the pressure (Boyle’s law).
Process c doubles the pressure because the absolute temperature is doubled (from 200. K to 400.
K).
Process d doubles the pressure because the moles of gas are doubled (28 g N2is 1 mol of N2).
Process b won’t double the pressure since the absolute temperature is not doubled (303 K to 333 K
