How much is the boiling point raised in degrees F* for an increase of 1 psi?

yes more pressure on water will increase the boiling temp.

Boiling point surely goes up when more pressure is applied. molecules when pressurized will be more packed together and will need more heat energy to make them change to gas.
In the case explained by xRay, the pressure is not increased but actually taken away from the water in a pump, that is why, at a lower pressure, the boiling point drops. Remember that in a pump, water is being pulled, not compressed.

Which one is about pressure and volume and then another about temperature and pressure. Charles's Law and Boyle's Law.
Anyway, yes increasing the ambient pressure will slightly increase the point at which water will go from liquid to vapor/gas--or its boiling point. I do not know the exact amount of time or temp involved, though.

It goes up. That's the reason for a pressurized cooling system on cars. Cavitation is caused by a poorly designed water pump. It creates air bubbles in the water which carry heat.

It actually goes down. In a water pump, the pressure can cause the water to boil at low temperatures, causing 'cavitation'.
