Which thermodynamic process gives maximum work?
Reversible adiabatic expansion/compression
Expression for work done in isothermal and adiabatic process?
For an isothermal process, the work done is given by W = nRT ln(V2/V1) where n is the number of moles, R is the gas constant, T is the temperature, and V1 and V2 are the initial and final volumes. For an adiabatic process, the work done is given by W = (P1V1 - P2V2)/(γ - 1) where P1 and P2 are the initial and final pressures, V1 and V2 are the initial and final volumes, and γ is the heat capacity ratio.
What is the work done in an isothermal process?
In an isothermal process, the work done is the product of the pressure and the change in volume of the system. This is because the temperature remains constant throughout the process, so the work done is solely determined by the change in volume.
What is the relationship between the work done in an adiabatic process and the change in internal energy of a system?
In an adiabatic process, the work done is equal to the change in internal energy of a system.
Is the work-done in isothermal system is zero why?
In an isothermal process, the temperature of the system remains constant. Since work done is the result of a change in energy, and the temperature does not change, there is no transfer of energy in the form of work during an isothermal process. Thus, the work done in an isothermal system is zero.

What are the four processes that make up the carnot cycle?
The Carnot cycle consists of four key processes: isothermal expansion, isothermal compression, adiabatic expansion, and adiabatic compression. In the isothermal expansion phase, the working substance absorbs heat from a hot reservoir while expanding, doing work on the surroundings. During isothermal compression, it releases heat to a cold reservoir while being compressed. The adiabatic processes involve the working substance expanding and compressing without heat exchange, allowing the temperature to change due to work done on or by the system.
What is true about isothermal process?
An isothermal process is one which does not take in or give off heat; it is perfectly insulated. Iso = same, thermal = heat. In real life there are very few isothermal processes. Heat loss accounts for most process inefficiencies.
What is energy is transferred to a gas as heat and work If there is no change in its internal energy the process is known as?
The process is known as an isothermal process. In an isothermal process, the energy transferred to the gas as heat and work results in no change in the gas's internal energy because the temperature remains constant throughout the process.
What is the work done in an isothermal process?
In an isothermal process, the work done is the product of the pressure and the change in volume of the system. This is because the temperature remains constant throughout the process, so the work done is solely determined by the change in volume.
Is isothermal expansion reversible under ideal conditions?
No. All processes involving heat transfer are not reversible, since they result in an increase in entropy. Isothermal expansion implies heat transfer to maintain the system at a constant temperature. Normally an expanding gas would cool if there were no heat entering the system. Adiabatic processes involve no heat transfer and are reversible. The temperature can (and usually does) change during an adiabatic process.
What is the relationship between the work done in an adiabatic process and the change in internal energy of a system?
In an adiabatic process, the work done is equal to the change in internal energy of a system.
Is the work-done in isothermal system is zero why?
In an isothermal process, the temperature of the system remains constant. Since work done is the result of a change in energy, and the temperature does not change, there is no transfer of energy in the form of work during an isothermal process. Thus, the work done in an isothermal system is zero.
What is the work done in an adiabatic process?
In an adiabatic process, no heat is exchanged with the surroundings. The work done is the change in internal energy of the system, which is equal to the pressure times the change in volume.
What are examples of isothermal process?
An isothermal process is a change in a system where the temperature stays constant (delta T =0). A practical example of this is some heat engines which work on the basis of the carnot cycle. The carnot cycle works on the basis of isothermal.
Which of the following is true of an isothermal process Temperature is constant W equals Q ΔU equals 0 Pressure is constant?
Temperature is constant during an isothermal process. The work done (W) is equal to the heat added (Q). The change in internal energy (ΔU) is zero for an isothermal process. The pressure can vary during an isothermal process, depending on the specific conditions.
