APH 107: Mechanics
Trending!
In physics we deal with physical quantities which are usually quantified by measuring. The process of measuring involves assigning a number to a physical quantity by comparing it with a standard. The standard quantity is called unit and used to measure the given physical quantity.

Early man used drawings to communicate even before he learnt to talk, write, or count. Incidentally, these ancient hieroglyphics (picture-writings) communicate as well today, as they must have done thousands of years ago, this fully supports the saying that “A picture is worth a thousand words” and in the era of computers we can add on to it or we may as well revise the saying to “A computer is worth a million pictures!”

SPH 302 LESSON 2: Equation of state of ideal gas
Trending!
Molecules at any given temperature do not all have the same speed but in fact, a distribution of speeds given by the MaxwellBoltzmann distribution. Two persons named James Maxwell and Ludwig Boltzmann came up with a theory to demonstrate how the speeds of the molecule are distributed for an ideal gas, which is the Maxwell-Boltzmann distribution theory

SPH 302 LESSON 3: The first law of thermodynamics
Trending!
When a system changes from a given initial state to a given final state, both the work W and the heat Q depend on the nature of
the process. Experimentally, however, we find that the quantity Q – W is the same for all processes. It depends only on the initial and final states, and does not depend at all on how the system gets from one state to the other. All other combinations of Q and W, including Q alone, W alone, Q + W, and Q - 2W, are path dependent; only the quantity Q – W is not.

One goal of physics is to understand why time has direction, and why one way processes are irreversible. Although this physics might seem disconnected from the practical issues of everyday life, it is in fact at the heart of any engine, such as a car engine, because it determines how well an engine can run.

SPH 302 LESSON 5: Heat engines and the Carnot cycle
Trending!
A heat engine, or more simply, an engine, is a device that extracts energy from its environment in the form of heat and does useful work. At the heart of every engine is a working substance. In a steam engine, the working substance is water, in both its vapor and its liquid form. In an automobile engine, the working substance is a gasoline–air mixture. If an engine is to do work
on a sustained basis, the working substance must operate in a cycle; that is, the working substance must pass through a closed
series of thermodynamic processes, called strokes, returning again and again to each state in its cycle.

SPH 302 LESSON 6: Helmholtz and Gibbs free energy
Trending!
Gibbs free energy, also known as the Gibbs function, Gibbs energy, or free enthalpy, is a quantity that is used to measure the
maximum amount of work done in a thermodynamic system when the temperature and pressure are kept constant. Gibbs free
energy is denoted by the symbol ‘G’. Its value is usually expressed in Joules or Kilojoules.

SPH 302 LESSON 7: Thermodynamic potentials
Trending!
Thermodynamic potentials are state functions that, together with the corresponding equations of state, describe the equilibrium
behavior of a system as a function of so-called “natural variables”. The natural variables are a set of appropriate variables that
allow to compute other state functions by partial differentiation of the thermodynamic potentials.

SPH 302 LESSON 8: Equillibrium between phases
Trending!
The generic phase diagram of a substance in the P-T coordinates is shown in figure 8.1a and b. Every point of this diagram is an equilibrium state. Different states of the system in equilibrium are called phases. The lines dividing different phases are called the coexistence curves. Along these curves, the phases coexist in equilibrium, and the system is macroscopically inhomogeneous. All three coexistence curves can meet at the triple point.
