This physics video tutorial provides a basic introduction into the surface tension of water.  Surface tension prevents small amounts of water from flattening out across a surface.  Rather, it causes water to minimize its surface area and as a result, water forms small beadlike droplets.  This video also discusses the capillary action of water as it is draw up through small tubes known as capillaries.  Surface tension can be calculated by divided the force per unit length required to increase the area of a fluid.  The surface tension opposes the force and attempts to minimize the area.  The work required to increase the area of a fluid by a force is the surface tension multiplied by the increase in area.  This video discusses the difference in the capillary effects between water and mercury.  Water rises above the surrounding fluid level in a thin glass tube where as mercury descends below that line.  The adhesive forces in water is greater than the cohesive forces.  In Mercury, the cohesive forces are greater than the adhesive forces.  Adhesive forces exist between different molecules and atoms.  Cohesive forces exist between the same type of molecules and atoms.

This video provides a basic introduction into bond energy and bond length.  It explains how to determine the bond length of a molecule given a graph that shows the potential energy of two atoms and the internuclear distance in nm.  It explains why atoms form bonds as they approach each other and why they repel each other when they get too close.

This chemistry video tutorial provides a basic introduction into the types of chemical bonds such as polar covalent bonds, nonpolar covalent bonds and ionic bonds.  It discusses the difference between ionic bonding and covalent bonding.  Ionic bonds can be identified by looking for a metal combined with a nonmetal.  Covalent bonds typically occur among 2 or more nonmetals.  Covalent bonding involves a sharing of electrons and ionic bonding forms as a result of a transfer of electrons from the metal to the nonmetal producing ions with opposite charge which are attracted to each other.  The electrostatic force of attraction produces the ionic bond that holds the cations and anions together.  Polar covalent bonds have unequal sharing of electrons between the atoms where as nonpolar covalent bonding have a relatively equal sharing of electrons between the atoms attached to the bond.  Polar covalent bonds typically have an electronegativity difference of 0.5 or more where as nonpolar covalent bonds have a value difference of 0.4 or less.

This statistics video tutorial provides a basic introduction into cumulative distribution functions and probability density functions.  The probability density function or pdf is f(x) which describes the shape of the distribution.  It can tell you if you have a uniform, exponential, or normal distribution.  The cumulative distribution function or cdf allows you to calculate the area under the curve to the left of some point of interest in order to evaluate the accumulated probability.

This physics video tutorial explains how to solve series and parallel circuits.  It explains how to calculate the current in amps through each resistor and the voltage in volts across each resistor with three resistors in series and parallel combination using a few simple formulas including ohm's law.  Parallel resistors form a current division circuit and series resistors form a voltage division circuit.  This video also explains how to calculate the electric power delivered by the battery in watts and the power absorbed by the resistors.
