Thermodynamics

Heat and Thermodynamics is one of the major contributions in Physics. Homework help bring this very important aspect of Physics Homework Help for all who have interested in the non-lasting events and concepts of Heat and Thermodynamics. For those many important topics are mentioned with full details and their solved examples, if there is any problem arising in any topic related to this aspect our expert tutors will help you 24×7 with 100% perfection. Now let us know what are the principles on which Heat and thermodynamics are based and how they will help us in day-to-day life and most importantly how they work and what are their main concepts.

Thermodynamics is the science that studies the transfer energy among different bodies. When a typical power plant produces electricity, water is heated to produce steam by burning fuel. Thermodynamics is a special macroscopic theory that does not involve use of underlying microscopic laws and is, therefore, valid regardless of the form of these laws. A thermodynamic system (or just system) is a specified macroscopic system, that is, a certain specified collection of particles. These same laws are equally important for the heat energies that propel millions of planes, trains and automobiles around the world. In fact, nearly all energy that powers our energy intensive economy involves, in some manner, the laws of thermodynamics. Scientific descriptions of nature can be categorized as microscopic or macroscopic. A microscopic description involves a discussion of the system using the properties of, and laws governing, atoms and molecules, while in a macroscopic description, one focuses on the large scale, properties of the system.

Heat is energy transferred as a result of a temperature difference. Temperature is a measure of the amount of molecular energy contained in a substance.

Work is a transfer of energy resulting from a force acting through a distance. The Second Law of Thermodynamics implies that heat will not transfer from a colder to a hotter body without some external source of energy. Conduction involves the transfer of heat by the interactions of atoms or molecules of a material through which the heat is being transferred.

Convection involves the transfer of heat by the mixing and motion of macroscopic portions of a fluid. Radiation, or radiant heat transfer, involves the transfer of heat by electromagnetic radiation that arises due to the temperature of a body. Heat flux is the rate of heat transfer per unit area.

Thermal conductivity is a measure of a substance’s ability to transfer heat through itself. Log mean temperature difference is the DT that most accurately represents the DT for a heat exchanger. The local heat transfer coefficient represents a measure of the ability to transfer heat through a stagnant film layer.

The overall heat transfer coefficient is the measure of the ability of a heat exchanger to transfer heat from one fluid to another. The bulk temperature is the temperature of the fluid that best represents the majority of the fluid which is not physically connected to the heat transfer site.

Some of its main topics are:

1. Convection and radiation

2. First of thermodynamics

3. Heat transfer processes

4. Haw of calorimetry

5. Laws of heat transfer

6. Second law of thermodynamics

7. Various laws and theories of gases

8. Zeroth law of thermodynamics
