What is meant by terms system and surrounding as used in thermodynamics illustrates with help of an example
Answers
Answer:
A thermodynamic system is a body of matter and/or radiation, confined in space by walls, with defined permeabilities, which separate it from its surroundings. The surroundings may include other thermodynamic systems, or physical systems that are not thermodynamic systems. A wall of a thermodynamic system may be purely notional, when it is described as being 'permeable' to all matter, all radiation, and all forces.
First Law The first law states that the amount of energy added to a system is equal to the sum of its increase in heat energy and the work done on the system. The first law is an example of the principle of conservation of energy.
Second Law The second law states that heat energy cannot be transferred from a body at a lower temperature to a body at a higher one without the addition of energy. Thus, warm air outside can transfer its energy to a cold room, but transferring energy from a cold room to the warm air outside requires extra energy (as with an air conditioner).
Third Law The third law states that the entropy of a pure crystal at absolute zero is zero. Since there can be no physical system with lower entropy, all entropy thus has a positive value by definition.
Zeroth Law The zeroth law states that if two bodies are in thermal equilibrium with some third body, then they are also in equilibrium with each other. This law has its name because it was implicitly assumed in the development of the other laws, and is in fact more fundamental than the others, but was only later established as a law itself.
Answer:
the universe is divided into two parts, the system and its surroundings. The system is the part of the universe which is under thermodynamic consideration, it is separated from the rest of the universe by real or imaginary boundaries. Everything in the universe that is not a part of the system is called surroundings
