Introduction
Infidelity is one of the leading causes of divorce. Based on studies, about 90% of divorce
cases involve infidelity (Zare, 2011). In

Introduction to Combustion
Combustion is the process by which reactants are oxidized to form products. For
this
course, the concern is combustion with the oxygen present in the air.

Second Law of Thermodynamics
The second law provides a principle by which to determine which processes are
more likely to occur, and what the final equilibrium state of the system would be,
particularly for those
Resistance in series
Often one must consider heat transfer through various mediums in series, one such
example is the heat flow from a gas on one side of a planar wall to the gas on the other
side. This heat transfer system may be analysed using the therm

The Ideal Gas Equation of State
It is from the kinetic theory of gases that the ideal gas law originates. The
law expresses the product of pressure and volume as proportional to the

Mixtures of Gases
We consider a mixture of gases, and look at how its composition is defined. Let
there be i components or species in the mixture. The total mass is the sum of the
individual masses of the species
