Monetary Evolution

 Monetary evolution refers to the changes and developments in the ways that people earn money over time. It encompasses the various methods, strategies, and technologies used to generate income, as well as the cultural and economic factors that influence these developments.

Throughout history, monetary evolution has been driven by advances in technology, changes in the economy, and shifts in societal values and beliefs. For example, the industrial revolution of the 18th and 19th centuries led to the rise of factory work and wage labor as a primary means of earning money. Similarly, the digital revolution of the 20th and 21st centuries has led to the growth of the gig economy, e-commerce, and online businesses.

Refrigerator and Reverse Carnot Cycle

Reverse Carnot Cycle 

       

Why Reverse Carnot cycle is an Ideal Cycle...?

      We know that every refrigerator work on the reverse Carnot cycle. as Carnot cycle consist adiabatic portion and isothermal portion one after another. In actual conduction required adiabatic portion speed of piston is high, and isothermal portion speed of piston s slow, which is impossible in actual condition That's why Reverse Carnot cycle is an ideal Cycle.

What are the processes in Carnot cycle...?

            It consist two reversible isothermal processes and two reversible adiabatic processes

As given

Process 1-2 :-Reversable isothermal heat absorption from low temperature...

Process 2-3 :- Reversible adiabatic compression

Process 3-4 :- Reversible isothermal heat rejection at high temperature

Process 4-1 :- Reversible adiabatic expansion

                    It means that heat absorption and heat rejection take place at constant temperature. Also compression and expansion take place at constant pressure.
