This property makes the surface of a liquid behave like a stretched, elastic film.
What is surface tension?
This is the attraction between molecules of different substances, such as water and glass.
What is adhesion?
This is the attraction between molecules of the same substance.
What is cohesion?
This is the curved surface of a liquid in a container or narrow tube.
What is a meniscus?
This branch of physics studies fluids at rest.
What is hydrostatics?
This is a push or pull that can change an object's motion.
What is force?
This is force applied per unit area.
What is pressure?
This principle says that a pressure change applied to a confined fluid is transmitted throughout the fluid.
What is Pascal's principle?
This phenomenon allows a liquid to rise or fall in a narrow tube because of adhesion and cohesion.
Answer: What is capillarity?
This is the upward force a fluid exerts on an immersed or floating object.
What is buoyant force?
This principle relates buoyant force to the weight of the fluid displaced by an object.
What is Archimedes' principle?
This branch of physics studies fluids in motion.
What is hydrodynamics?
This property describes a fluid's resistance to flowing.
What is viscosity?
This phenomenon occurs when local pressure in a liquid drops enough for vapor bubbles to form.
What is cavitation?
This principle states that, for steady incompressible flow, the product of cross-sectional area and fluid
speed remains constant.
What is the principle of continuity?
Water has a density of 1,000 kg/m3. Using g = 9.8 m/s2, what is the gauge pressure at a depth of 1.5 m?
What is 14,700 Pa? Calculation: P = ρgh = (1,000)(9.8)(1.5) = 14,700 Pa.
