A 1.0 L container of liquid nitrogen is kept in a closet measuring 1.0 m by 1.0 m by 2.0 m. Assuming that the container is completely full, that the temperature is 25 degrees Celsius, and that the atmospheric pressure is 1.0 atm, calculate the percent (by volume) of air that is displaced if all of the liquid nitrogen evaporates. (Liquid nitrogen has a density of 0.807 g/mL).

25.0 ml of liquid nitrogen (density 0.807 g/ml) is poured intoacylindrical container with a radius of 11.5 cm and a length of21.3cm. The container initially only contains air (molar mass 28.8g/mol) at a pressure of 760 mmHg and a temperature of 285K. If theliquid nitrogen completely vaporizes, what is the total force inpounds (lb) on the interior of the container at 285K?

Liquid nitrogen has a density of 0.808 g/mL and boils at 77 K.Researchers often purchase liquid nitrogen in insulated 185 Ltanks. The liquid vaporizes quickly to gaseous nitrogen (which hasa density of 1.15 g/mL at room temperature and atmosphericpressure) when the liquid is removed from the tank. Suppose thatall 185 L of liquid nitrogen in a tank accidentally vaporized in alab that measured 10.00 m times 10.00 m times 3.50 m.
