What is the importance of the carnot cycle?What is it for?

Expert Solution

Sadi Carnot was a French physicist who proposed an “ideal” cycle for a heat engine in 1824. Carnot cycle explains the working of a heat engine that uses reversible processes. According to Carnot, a cycle that is comprised of completely reversible processes only, would give the maximum efficiency i.e., maximum amount of net work for a given heat input.

Carnot cycle consists of four reversible processes. Two of these processes are reversible adiabatic processes (2 and 4) and the rest two other processes are reversible isotherms (1 and 3). The p-V diagram of a Carnot engine is shown below:

The efficiency of an ideal Carnot engine is maximum and is given by the simple expression,

An engine operates in a Carnot cycle. At point A in the cycle, 2.34 mol of a monatomic ideal gas has a pressure of 1,400 kPa, a volume of 10.0 L, and a temperature of 720 K. The gas expands isothermally to point B and then expands adiabatically to point C, where its volume is 24.0 L. An isothermal compression brings it to point D, where its volume is 15.0 L. An adiabatic process returns the gas to point A....

A Carnot cycle consists of a cycle of 4 processes, in the order: 1) isothermal expansion at T(hot)=90oC, 2) adiabatic expansion to T(cold)=30oC, 3) isothermal contraction at T(cold), 4) adiabatic contraction to the original state. The gas in the system can be treated as a monotonic ideal gas Part A. After one complete cycle, what is the change in thermal energy of the gas in the system? Part B. After a complete cycle what is the change in entropy? (The...

Can someone please explain the Carnot Cycle graph in terms of what equations to use and the concepts. This is what I think but I keep getting mixed up: Path A to B which is Reversible Isothermal Expansion, Delta U= 0, and according to first law Q= -W and we use RTln V2/V1 for W? In path B to C, the gas expand Adiabatically, so Q= 0 and Delta U= - W. Since it is expansion so the work will be...

a. Refrigerators make use of the heat cycles, such as the Carnot cycle, but in order to remove heat from the cold source (fridge) and put that energy into the hot source (the enrivonment), another energy source must be added to the system to make this occur. The minimum energy to be supplied follows the equation given below. Find an expression for the coefficient of performance in terms of Th and Tc. coefficient of performance (c) = heat...

A mole of an ideal gas goes through a cycle of a Carnot engine. Draw the pressure vs volume and entropy vs temperature planes for this cycle. What do the diagrams look like when the efficiency of the cycle is 50% and 99%. Then Calculate the work done per cycle by the gas and find the efficiency of the cycle.
