Which basic principle influences how all HVACR systems work?

A) A decrease in pressure increases the boiling point of liquid, the temperature at which the liquid turns to a gas.

B) An increase in pressure can lower the boiling point of a liquid and change the temperature at which it turns to a gas.

C) An increase in pressure can increase the boiling point of a liquid, the temperature at which the liquid turns to a gas.

D) Pressure affects boiling point and evaporation in an unpredictable way, so it must not be considered in HVACR equipment.
