The force exerted by trapped liquid refrigerants as its temperature increases is known as?

• A. Hydraulic pressure
• B. Vapor pressure
• C. Hydrostatic pressure
• D. Tensile stress

Answer: (C)

Hydrostatic pressure is the pressure exerted by a stationary liquid due to the weight of the liquid above a point. In a trapped liquid refrigerant, heating causes the liquid to expand, raising the height of the liquid column against the container walls, which increases this pressure. The concept hinges on P = rho g h, where raising the column height (h) or changing density (rho) with temperature affects the pressure the liquid pushes on the surroundings. Vapor pressure is the pressure from the vapor phase in equilibrium with the liquid, which is a different idea, and tensile stress relates to solids under pulling forces, not a liquid column. Hydraulic pressure is about pressure transmission in a fluid-filled system, not the static pressure from a liquid column itself.
