PHYSICS CHAPTER 11

• Absolute pressure


  The sum of gauge pressure and atmospheric pressure
• Adhesive forces


  The attractive forces between molecules of different types
• Archimedes' principle


  The buoyant force on an object equals the weight of the fluid it displaces
• Buoyant force


  The net upward force on any object in any fluid
• Capillary action


  The tendency of a fluid to be raised or lowered in a narrow tube
• Cohesive forces


  The attractive forces between molecules of the same type
• Contact angle


  The angle between the tangent to the liquid surface and the surface
• Density


  The mass per unit volume of a substance or object
• Diastolic pressure


  The minimum blood pressure in the artery
• Diastolic pressure


  Minimum arterial blood pressure; indicator for the fluid balance
• Fluids


  Liquids and gases; a fluid is a state of matter that yields to shearing forces
• Gauge pressure


  The pressure relative to atmospheric pressure
• Glaucoma


  Condition caused by the buildup of fluid pressure in the eye
• Intraocular pressure


  Fluid pressure in the eye
• Micturition reflex


  Stimulates the feeling of needing to urinate, triggered by bladder pressure
• Pascal's Principle


  A change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container
• Pressure


  The force per unit area perpendicular to the force, over which the force acts
• Pressure


  The weight of the fluid divided by the area supporting it
• Specific gravity


  The ratio of the density of an object to a fluid (usually water)
• Surface tension


  The cohesive forces between molecules which cause the surface of a liquid to contract to the smallest possible surface area
• Systolic pressure


  The maximum blood pressure in the artery
• Systolic pressure


  Maximum arterial blood pressure; indicator for the blood flow
