Each increase in cooling system psi raises the boiling point of the coolant by
(A) 1 degree F.
(B) 2 degrees F.
(C) 3 degrees F.
(D) 5 degrees F.

Answer 1

(A) 1 degree F

Step-by-step explanation:

Each increase of 1 psi (pound per square inch) in the cooling system raises the boiling point of the coolant by approximately 1 degree Fahrenheit. This relationship is due to the fact that increasing pressure raises the boiling point of a liquid. Therefore, for every 1 psi increase in cooling system pressure, the boiling point of the coolant increases by 1 degree Fahrenheit.
