Study Notes
-
Three-dimensional regular configuration: shape and volume well-defined, incompressible, molecules/atoms fixed in a grid.
-
Intermolecular forces: important in condensed matter, weaker than ionic, covalent, and metallic bonds.
-
Intermolecular forces: main types are hydrogen bonds and Van der Waals forces (dipole-dipole, dipole-induced dipole, and London dispersion forces).
-
Surface tension: due to net force towards interior of liquid caused by molecular forces.
-
Capillarity: occurs when intermolecular forces of a liquid are lower than its internal cohesion or the adhesion of the liquid to the material of the tube.
-
Hydrodynamics: pressure is defined as the normal force per unit area acting on a surface.
-
Pascal's Principle: a change in pressure at any point in a fluid at rest is transmitted undiminished to all points in the fluid.
-
A fluid's density is the mass per unit volume.
-
Hydraulic press: consists of two communicating cylinders filled with a fluid, with pistons and pressure is transmitted completely and instantaneously to the surface upon force application.
-
Equilibrium: the net force acting on a system is zero.
-
Surface tension and hydrostatic pressure are involved in a fluid's behavior in various physical phenomena.
-
The text discusses the fundamentals of hydrostatics, which deals with fluids at rest.
-
The hydrostatic equation states that the pressure difference between two points of a fluid at rest is given by the sum of the fluid density and the product of the pressure difference and the height difference between the two points.
-
Manometric pressure difference refers to the pressure difference measured in high-pressure systems.
-
The pressure increases with depth in a fluid.
-
The pressure difference between two points only depends on the height difference between them, assuming constant density.
-
The pressure at the free surface of a fluid is equal to the atmospheric pressure.
-
The concept of communicating vessels applies to containers connected by a homogeneous liquid, where the liquid levels in the containers adjust to equalize the pressure.
