Three moles of an ideal gas (with temperature-independent Cp =(7/2)R, Cv = (5/2)R) is contained in a horizontal piston/cylinderarrangement. The piston has an area of 0.1m^2 and mass of 500 g.The initial pressure in the piston is 101 kPa. Determine the heatthat must be extracted to cool the gas from 375 C to 275 C at a.)constant pressure; b.) constant volume.
