Can two adiabatic curves intersect?

Yes two (different) adiabatic paths can intersect in a plot. However, for this to be possible, at least one of them has to be irreversible. For different reversible adiabatic processes involving the same working substance, their plots cannot intersect.

Can two reversible adiabatic lines intersect each other?

Introduction: Since two constant property lines can never intersect each other, it is inferred that a reversible adiabatic path must represent some property, which is yet to be identified.

Why are adiabatic curves steeper than isothermal curves?

The adiabatic curve is steeper than the isothermal curve, in both the processes of expansion and compression. To reach a same height in a longer distance means lower slope of the line. Hence adiabatic curve is more steeper than isothermal curve.

How do you know if a curve is adiabatic?

The curve showing the relation between pressure and volume of a given mass of gas when the flow of heat into or out of the gas is stopped is called its adiabatic curve. If isothermal and adiabatic curves be plotted on the same p–v diagram (Fig. 8.4), then the adiabatic curve would be steeper than the isothermal curve.

Which property of a system is constant in reversible adiabatic process?

Entropy remains constant in an adiabatic process which is also reversible.

Which property of a system is constant in reversible adiabatic process a pressure B Volume C temperature D entropy?

Adiabatic processes are those in which there is no transfer of energy between the system and the surrounding. Therefore the total heat of the system remains conserved in an adiabatic process.

What is the difference between adiabatic and isothermal curve?

The major difference between these two types of processes is that in the adiabatic process, there is no transfer of heat towards or from the liquid which is considered. Where on the other hand, in the isothermal process, there is a transfer of heat to the surroundings in order to make the overall temperature constant.

When a gas expands adiabatically what happens?

When an ideal gas is compressed adiabatically (Q=0), work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its temperature drops.

Why is the PV curve for adiabatic?

In an adiabatic expansion as there is no heat loss or gain to or from the surroundings (q=0) the energy needed for the work of expansion against the external pressure must come from the internal energy of the gas. This results in a lowering of the temperature. A curve of reversible adiabatic p vs.

Why does the entropy remains constant in reversible adiabatic process?

The entropy is merely transferred from the system to the surroundings. Actually in all adiabatic compression process entropy does not remain constant. Entropy always accompanies heat transfer. Hence for only reversible adiabatic procedure entropy remains constant also known as an isentropic procedure.

Which property of the system does not change is an adiabatic process?

Can two reversible adiabatic processes intersect?

For different reversible adiabatic processes involving the same working substance, their plots cannot intersect. See Fig 1. Now, if you could have two reversible adiabatic processes intersect and be connected by a reversible isothermal process, there would be a violation of the second law.

Why do adiabatic curves never cross?

For adiabatic curves, each curve traces part of the locus of states of a given mass of fluid having a given enthalpy, which, on a 2-dimensional chart, like P-V, is a curve (a hyperbole for P-V). Different curves represent different energetic states, so they never cross.

Can two adiabatic paths intersect in a plot?

To answer your first question, yes two (different) adiabatic paths can intersect in a plot. See State A in Fig 2. However, for this to be possible, at least one of them has to be irreversible. For different reversible adiabatic processes involving the same working substance, their plots cannot intersect.

Can the pressure remain constant during an adiabatic process?

The answer is no, During the adiabatic process the there heat flow between system and surrounding…. i.e. dQ = 0 then there will be no work done during the process.. Hence, the pressure cannot remain constant during adiabatic process.. What is an adiabatic process?
