Air is in a piston/cylinder setup at 2000 kPa pressure and 290 K temperature (see below figure). Air reaches 1000 kPa pressure and 400 K after an expansion process during which transferred heat to the air is 100 kJ/(kg air). Determine a) the per unit mass entropy change of air (kJ/kg-K) and b) per unit mass work performed by the air. Air is an ideal gas with variable specific heats. (for air R= 0.287 kJ/kg-K).

Important instruction: This question uses the last three-digit value (L3D) of individual student matrix number. For example, if the matrix number is CD180264 then the L3D value is 264 (since the last three digits is 264). Some data require multiplication of the L3D value, for examAdditional instruction: These questions use the last three-digit value (L3D) of individual student matrix number.
