Assuming the non-pressurized boiling point of a 50-50 mix of coolant is 6°C higher than the boiling
point of water (100°C), and every one psi increase in pressure will raise the cooling system boiling
point by 1 C. Calculate the coding system boiling point if a 15 psi pressure cap is used. How will
the value change if a 12 psi cap is used instead. If pure water is used rather than a 50-50 mix, then
how is the boiling point changed? What about the freezing point?
