The density of nitrogen gas (N2) at standard temperature and pressure (STP, 0°C and about 1atm) is 1.25 kg/m3, while the density of liquid nitrogen at atmospheric pressure is 0.81 x 103kg/m3. Let D denote a typical distance between nitrogen molecules in its gas (i) Assuming that the nitrogen atoms in the liquid are basically touching each other, esti- ii) Using the ideal gas equation of state determine the volume of 1 mole of gas at STP. phase and d...
The density of a gas under NORMAL conditions (STP, 273K and 1atm) is 2.4 grams/Liter. There is an ideal gas inside a 20L volume container at a temp of 5 degrees celcius. The gas is allowed to leave the container, causing the pressure inside to decrease by 0.85 atm. (the temperature inside remains constant). What is the mass of the gas that is released?
What is the density of air at 75 °F and 1atm pressure? Express in lbm/ft3 and kg/m3.
Air undergoes an isentropic process from p1=1atm, T1=540R to a final state where the temperature is T2=1160R. employing the ideal gas model, determine the final pressure p2, in atm. Assume a constant specific ratio k evaluated at the mean temperature.
