Question:
With a pressure gauge you measure the pressure difference between the pressure in a vessel and the pressure outside (so you measure the overpressure!). At any given day, atmospheric pressure is 78 cm Hg. A vessel is filled with N2 gas (molar mass 28 g / mol). The pressure gauge on the vessel indicates 240 cmHg as an indication of the pressure of the gas in the vessel. The gas in the vessel has a temperature of 15 ° C. When the vessel cools down to a temperature of -1 ° C, the pressure gauge indicates a pressure of:
Select the correct answer in the following list
a) 222.3 cm Hg
b) 992. mmHg
c) 5688. cm Hg
d) 791.0 mmHg
