### A Carnot engine converts one fifth of the heat input into work. If the sink temperature is reduced by 80o C, the efficiency gets doubled. Find the source and the sink temperature. Also give the consequences of the Carnot cycle.

Maximum efficiency of an engine working between temperatures T2 and T1 is given by the fraction of the heat absorbed by an engine which can be converted into work is known as efficiency of the heat engine. Mathematically, Efficiency, η = (T2 - T1) / T2 ...

### Define Carnot Theorem and also give its proof.

Carnot theorem states that no heat engine working in a cycle between two constant temperature reservoirs can be more efficient than a reversible engine working between the same reservoirs. In other words it means that all the engines operating between a given constant temperature source ...

### Calculate the net efficiency of a Heat Engine?

Efficiency of a heat engine: The fraction of the heat absorbed by an engine which can be converted into work is known as efficiency of the heat engine. Mathematically, Efficiency, η = w / q2 = (T2 - T1) / T2 ……………. (1) As (T2 - T1) / T2 ...

### Explain Cyclic Process with example.

Cyclic process: When a system returns to its original state after completing a series of changes, then it is known that a cycle is completed. This process is known as cyclic process. In a cyclic process the initial and the final state is same. As the ...

### Define the spontaneous processes with example

Spontaneous processes: A spontaneous process is one in which heat is transferred through a finite temperature. Spontaneous process is also known as irreversible process because these processes take place at very fast rate. All the natural processes are spontaneous processes. Examples of irreversible processes are as follows: 1) Relative ...
