what is thernodynomics??

Question

can any one explain what thermodynatice means and how it effect engineering. thank u i really appreciate if any one can help me.

Answer 1

it has alot of means

Answer 2

Thermodynamics is the study of the inter-relation between heat, work and internal energy of a system.
In simplest terms, the Laws of Thermodynamics dictate the specifics for the movement of heat and work. Basically,
the First Law of Thermodynamics is a statement of the conservation of energy,
the Second Law is a statement about the direction of that conservation - and the
Third Law is a statement about reaching Absolute Zero (0° K).
Briefly no work can be done without using energy so you have to have energy to do work.

Answer 3

Go Engineers...woot! Anyway thermodynamics is the dtudy of the conversion of heat into other forms of energy. basically it is the study of how heat is transfer. in college it is necessary for everyone to take heat and mass transfer (or so mizzou tells me). You need to know how heat is transfered to certain materials, metals plastics, etc. to know how they stand up in that environment and know if they will be able to withstand these temperatures. As a biological engineer, when you implant a stent or something you want to make sure that the stent will be able to stand the body's temperature without deteriorating

Answer 4

Thermodynamics is a branch of physics which deals with the energy and work of a system on a large scale.

Thermodynamics is a branch of physics which deals with the energy and work of a system. It was born in the 19th century as scientists were first discovering how to build and operate steam engines. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. Small scale gas interactions are described by the kinetic theory of gases. The methods compliment each other; some principles are more easily understood in terms of thermodynamics and some principles are more easily explained by kinetic theory.

There are three principal laws of thermodynamics which are described on separate slides. Each law leads to the definition of thermodynamic properties which help us to understand and predict the operation of a physical system. We will present some simple examples of these laws and properties for a variety of physical systems, although we are most interested in thermodynamics in the study of propulsion systems and high speed flows. Fortunately, many of the classical examples of thermodynamics involve gas dynamics. Unfortunately, the numbering system for the three laws of thermodynamics is a bit confusing. We begin with the zeroth law.

The zeroth law of thermodynamics involves some simple definitions of thermodynamic equilibrium. Thermodynamic equilibrium leads to the large scale definition of temperature, as opposed to the small scale definition related to the kinetic energy of the molecules. The first law of thermodynamics relates the various forms of kinetic and potential energy in a system to the work which a system can perform and to the transfer of heat. This law is sometimes taken as the definition of internal energy, and introduces an additional state variable, enthalpy. The first law of thermodynamics allows for many possible states of a system to exist. But experience indicates that only certain states occur. This leads to the second law of thermodynamics and the definition of another state variable called entropy. The second law stipulates that the total entropy of a system plus its environment can not decrease; it can remain constant for a reversible process but must always increase for an irreversible process.

Answer 5

thermodynamics?


The physical theory of heat and energy distribution in the universe. The two important laws of thermodynamics state that the total energy of the universe is constant and energy can neither be made nor destroyed, and that the distribution of energy in the universe over time proceeds from a state of order to a state of disorder (entropy increase).
