how does thermodynamics deal with systems&surroundings???????

Question

please let me know yar.........

Answer 1

In thermodynamics, a thermodynamic system, originally called a working substance, is defined as that part of the universe that is under consideration. A real or imaginary boundary separates the system from the rest of the universe, which is referred to as the environment or surroundings (sometimes called a reservoir.) A useful classification of thermodynamic systems is based on the nature of the boundary and the quantities flowing through it, such as matter, energy, work, heat, and entropy. A system can be anything, for example a piston, a solution in a test tube, a living organism, a planet, etc.

Answer 2

Thermodynamics deals with the flow of energy from one system to another and thus involves all of creation.

Answer 3

What you focus your attention on is the system. Everything else is the surrounds.

Example; if you do a reaction in a bomb calorimeter, reactants and products are the system, while the water etc to which heat is transferred is surrounds.
