Question

A closed piston cylinder device contains 0 2 kg of air initially at 300 K and 100 kPa The air is now slowly compressed in an isothermal process to a final pressure of 250 kPa Assume the air is an ideal gas with constant specific heat Cp 1 004 kJ kg K Cv 0 717 kJ kg K The molecular weight for air is 29 kg kmol A Draw a schematic and list the necessary assumptions B Determine the volume in m of the air at the initial state C Determine the temperature and volume of the air at the final state D Determine the work in kJ during the process Is the work done by the air or on the air F Determine the heat transfer in k I during the process is a heat input or output
