Consider the ideal gas equation of state: PV = mRT = nRT R where R = , R is universal gas constant = 8.314 kJ/kmol-K and M is the molecular weight M' A closed piston-cylinder system contains air (molecular weight M = 28.97 kg/kmol) at a temperature of 27C and an absolute pressure of 100 kPa. (a) Determine the specific volume of air, in m/kg. (2 points) Air in the cylinder is heated without changing its temperature until its volume doubles. (b) Does the specific volume of air in the cylinder decrease, increase, or remain the same? Explain. (4 points) (c) Does the pressure of air in the cylinder decrease, increase, or remain the same? Explain.
