C)Let's say that the temperature at which your engine parts begin to melt is 3500 °C. Can your engine handle the temperature you calculated in part b.? Explain your answer.
D)Your engine has an elaborate cooling system that allows it to maintain a reasonable temperature by transferring heat to a coolant. One coolant option may be water. Knowing that water has a high specific heat, freezes at 0 °C, and boils at 100 °C, discuss the pros and cons of using water as your coolant.
