In an isothermal process, a PV diagram is significant because it shows the relationship between pressure and volume while keeping the temperature constant. This helps to visualize how the gas behaves under these conditions and can be used to calculate work done and energy transfer in the system.

What does an isothermal PV diagram illustrate about a thermodynamic process?
An isothermal PV diagram illustrates a thermodynamic process where the temperature remains constant.
What is the difference between isothermal and hyperbolic process?
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.
What is the significance of the area under a PV diagram in thermodynamics?
The area under a PV diagram in thermodynamics represents the work done by a system during a process. It is a measure of the energy transferred to or from the system in the form of work. This is important in understanding the efficiency and performance of thermodynamic processes.
Can we calculate work done in reverisbleprocess in term of pv diagram?
Yes, work done in a reversible process can be calculated using the area under the curve on a PV diagram. This is because the work done is equal to the area enclosed by the process curve on a PV diagram.
What is the significance of the Rankine cycle in thermodynamics and how does its PV diagram illustrate the energy conversion process within a power plant?
The Rankine cycle is important in thermodynamics because it is a theoretical model that represents the ideal process for converting heat into mechanical work in a power plant. The PV diagram of the Rankine cycle shows the stages of this energy conversion process, including heat input, expansion, heat rejection, and compression. By analyzing the PV diagram, engineers can optimize the efficiency of power plants by understanding how energy is transferred and transformed throughout the cycle.

What does the PV diagram of an isothermal expansion illustrate?
The PV diagram of an isothermal expansion illustrates the relationship between pressure and volume during a process where the temperature remains constant.
What are the key differences between adiabatic and isothermal processes on a PV diagram?
In an adiabatic process, there is no heat exchange with the surroundings, leading to steeper slopes on a PV diagram compared to an isothermal process where temperature remains constant. This results in different shapes and behaviors on the PV diagram for each process.
What isothermal process?
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
What is the difference between isothermal and hyperbolic process?
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.

Which process will lead to larger work output isothermal process or polytropic process with n1.25?
The process equation for this is PV up to the nth power which equals C. The polytrophic process is 1.25 which is the n in the equation.
How do you use the ideal gas law to derive the equation for the function PV for an ideal gas undergoing an isothermal process?
The ideal gas equation says that pV=nRT. p = pressure V = volume n = number of moles R = gas constant T = temperature Keeping temperature constant and presuming we don't add or subtract any of the gas, thus keeping the number of moles constant, we have: pV=constant or V=1/const. Where const. = nRT. And this gives the specific curve.

What is the significance of the adiabatic process on a PV diagram?
The adiabatic process on a PV diagram is significant because it represents a thermodynamic process where no heat is exchanged with the surroundings. This means that the change in pressure and volume of the system is solely due to work done on or by the system, without any heat transfer. Adiabatic processes are important in understanding the behavior of gases and the efficiency of certain processes, such as in engines and refrigeration systems.
