Air contained in a rigid insulated tank fitted with a

Air contained in a rigid, insulated tank fitted with a paddle wheel, initially at 4 bar, 40oC and volume of 0.2 m^3, is stirred until its temperature is 500 K. Assuming the ideal gas model for the air, determine the amount of entropy produced, in kJ/K. Assume variable specific heats (data from Table A-22).
