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.

How does the volume change in an isentropic process?
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.

What is the main isentropic thermodynamic process?
Practically there is no reversible isentropic process but to make the concept easier to be understood, you have to assume the following: * Ideal gas. * no friction losses. * Adiabatic preocess (no heat gain, no heat loss). API 520 part 1 Appendix B assumes that the vapor expansion through a nozzle or a pressure relief valve follows an isentropic path.
What is known as carnot heat engin?
carnot's heat heat engine is also known as ideal heat engine.because in carnot's the precess is reversible .Total heat converted into work . The efficiency is maximum for carnot's heat engine.
What are the condition for ideal fluid?
1.Isothermal expansion at a high temperature AB 2.Adiabatic expansion as the temperature falls to a lower rule BC 3.Isothermal compression at lower temperature CD 4.Adiabatic compression as temperature increase to initial high volume DA
What factors reduce the efficiency of heat engine from its ideal value?
This inefficiency can be attributed to three causes. There is an overall theoretical limit to the efficiency of any heat engine due to temperature, called the Carnot efficiency. Second, specific types of engines have lower limits on their efficiency due to the inherent irreversibility of the engine cycle they use. Thirdly, the non ideal behaviour of real engines, such as mechanical friction and losses in the combustion process causes further efficiency losses.OR· friction of moving parts· inefficient combustion· heat loss from the combustion chamber· departure of the working fluid from the thermodynamic properties of an ideal gas· aerodynamic drag of air moving through the engine· energy used by auxiliary equipment like oil and water pumps· inefficient compressors and turbines· imperfect valve timing
What is entrophy?
Entropy is:It is denoted by S.It is a state function and ΔS is independent of path.Entropy is a measure of the degree of randomness or disorder in a system.Greater the disorder of a system, the higher is the entropy. The decrease of regularity in structure means increase in entropy.Crystalline solid is the state of lowest entropy (most ordered) and the gaseous state is a state of highest entropy.As the temperature increases, randomness increases, and thus, entropy increases.For a reversible reaction, entropy change (ΔS)(for a reversible reaction)At equilibrium, ΔS = 0Entropy of a spontaneous reaction increases till it reaches the maximum, and at equilibrium, ΔS = 0Entropy is a state property. Therefore, entropy change for a reversible process is given byFor reversible and irreversible isothermal expansion of an ideal gas (that is under isothermal conditions), ΔU = 0. But is not zero for the irreversible process.Main definition are stated according to http://wiki.answers.com/Q/FAQ/8454.Thermodynamics is the study of energy conversion between heat and mechanical work which leads to the macroscopic properties such as temperature, volume, and...

What happens to a population under ideal conditions?
Under ideal conditions, population increases.
Isotherm in physics?
Isotherms in thermal physics are the lines on a pressure versus volume graph for an ideal gas, where the pressure and volume are alowwed to vary but temperature is kept constant. They are the result of Isothermal expansions or contracions of ideal gasses.
