can i know what is the thermodynamics?and what is the laws of that?

Answer 1

0. If two thermodynamic systems are in thermal equilibrium with a third, they are also in thermal equilibrium with each other.

1. In any process, the total energy of the universe remains constant.

2. There is no process that, operating in a cycle, produces no other effect than the subtraction of a positive amount of heat from a reservoir and the production of an equal amount of work.

3. As temperature approaches absolute zero, the entropy of a system approaches a constant.

Read http://en.wikipedia.org/wiki/Laws_of_thermodynamics for more on what thermodynamics is and for explanations of the laws.

Answer 2

thermodynamics is the study of the relationship between energy and matter specifically its motion. there is the zeroth law of thermodynamics.it states that if two thermodynamic systems are in thermal equilibrium with a third, they are also in thermal equilibrium with each other.just anlyze that.the first law of thermodynamics is the law of conservation of energy.in any process, the total energy of the universe remains constant.energy cannot be created nor destroyed.it can only be transformed from one form to another.the second law states that operating in a cycle, a process produces no other effect than the subtraction of a positive amount of heat from a reservoir and the production of an equal amount of work.the third law states that ss temperature approaches absolute zero (0 Kelvin), the entropy (disorderliness of particles in motion) of a system approaches a constant.

Answer 3

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 4

There are 3 of them but some people say that there's only 2.

The third one is "entropy", a measure of the disorder of the universe. Some people say it's covered in law #2.

Now go to wikipedia.

Answer 5

Basically -

Law 1 - You can't win in this game

Law 2 - You can't break even in this game

Law 3 - You can't get out of the game
