Question

3) Explain the following processes cyclic process with example and non cyclic process with example​

Answer 1

Answer:

The cyclic and non- cyclic processes are very important topics in thermodynamics . Here I will give you brief description about cyclic and non- cyclic processes which is generally use in thermal science.

cyclic process :- When a system returns to it's original state after completing a series of change , then it is known that a cyclic is completed.

In cyclic process the initial and the final state is same. For cyclic process the net change in internal energy (∆U) is zero.These cyclics are ideal in nature.

According to First law of thermodynamics:-

∆Q = ∆U + W

For cyclic process, ∆U = 0 then,

∆U = 0 , ∆Q = W

Example :- The Carnot cycle is best example of cyclic process.

Non- cyclic process :- When a system doesn't returns to its original state because of irreversibilities present in system ( like friction ), then such type of process is known as non- cyclic process. All the real cyclics behave as non- cyclic process.

First law of thermodynamics is :-

∆Q = ∆ U + W

Example :- The boiling of water is best example of non- cyclic process.
