Calculate the pressure at a height of 8000 m above sea-level if the atmospheric pressure is 101.3 kN/m² and temperature is 15°C at the sea-level assuming (i) air is incompressible, (ii) pressure variation follows adiabatic law, and (iii) pressure variation follows isothermal law. Take the density of air at the sea-level equal to 1.285 kg/m³. Neglect variation of gwith altitude. [Ans. (i) 607.5 N/m², (ii) 31.5 kN/m² (iji) 37 45 kN/m² 1
Next, using the data set below which was collected using a closed system soap bubble within a chamber, plot pressure vs. volume on a standard graph. To successfully complete this exercise you will need to graph the data set using a graphing program that allows curve fitting and the equation of the best fit function to the data. Pressure (kPa) should be plotted on the y-axis, while volume (ml) should be plotted on the x-axis. Compute the product of pressure and volume and enter your results into the 3rd column. If as Boyle's Law suggests, volume is inversely related to pressure, as pressure is increased within the chamber, the volume of gas trapped within the soap bubble will decrease. The product of pressure times volume (PV) should theoretically be a constant (k). Note: Pressure can be expressed in many different units. 1 atmosphere is considered air pressure at sea level on Earth. 1 atm = 101.3 kPa = 1.013 x 105 N/m² 1 atm = 1.013 bar = 14.7 lb/in² = 706 torr = 760 mm Hg Once you…
