Answer to Question #226655 in English for Zee

Question

Oxygen (molar mass 32 kg/kmol) expands reversibly in a cylinder behind a piston at a constant pressure of 3 bar. The volume initially is 0.0102 m³ and finally is 0,0302 m³ , the initial temperature is 16.09 ⁰C. Calculate the specific gas constant with the correct unit to two decimal places. Assume oxygen to be a perfect gas and take the specific heat at constant pressure as = 0.917kj/kg K and molar gas constant as = 8,314 J / kmol K.
