Question

9. A cooling system with a 50/50 mix of water and ethylene glycol in a cooling system with a 15 pound pressure cap will have what boiling point?

CA. 217" F
OB. 257° F
OC. 212° F
OD. 227' F

Answer 1

A cooling system with a 50/50 mix of water and ethylene glycol in a cooling system with a 15 pound pressure cap will have a boiling point of approximately 227°F (OD).

Answer 2

Answer is b

Using a coolant boiling point chart, we can find that at 15 psi, a 50/50 mixture of water and ethylene glycol has a boiling point of approximately 257°F.

Therefore, the answer is option B: 257° F.
