(a) Plot the specific heat of water versus the water temperature for temperatures ranging from 80 to 120°C. Add a second curve on the same graph, but use a 50:50 blend of water and ethylene glycol as the coolant. (b) What change in the design of the cooling system would be needed to compensate for the reduced specific heat of the coolant containing antifreeze?
