Is isothermal work greater than adiabatic?
Both start from the same point A, but the isothermal process does more work than the adiabatic because heat transfer into the gas takes place to keep its temperature constant. This keeps the pressure higher all along the isothermal path than along the adiabatic path, producing more work.
Which process has highest work done?
The work done in adiabatic process is maximum. This is because the rate of pressure increase is faster in the adiabatic process as all the energy of the work done on the system increases its internal energy.
Why work done is maximum in isothermal process?
If the external pressure becomes equal to the pressure of the gas, there will be no change in the volume and thus ΔV = 0. The work done is also zero. If Pext is more than the pressure of the gas cannot expand. Therefore work done in an isothermal reversible expansion of an ideal gas is maximum work.
Why is adiabatic steeper than isothermal?
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.
Why is adiabatic work less than isothermal work?
It takes heat from surrounding and the temperature remains constant throughout the cycle . The second container is insulated (No heat can be added/removed) in a adiabatic expansion. This will do less work than isothermal , because it solely depends on its internal energy to do work .
Why work done in adiabatic process is less than isothermal process?
is the heat energy conduction. , work done on it and its temperature increases and the gas does work and its temperature drops. Since, both Pressure and Temperature decreases hence pressure is less than the pressure of isothermal process. So, Work done in reversible adiabatic is less.
What is isothermal work done?
Work done in Isothermal process In an isothermal process temperature remains constant. That is, in an isothermal expansion, the gas absorbs heat and does work while in an isothermal compression, work is done on the gas by the environment and heat is released.
Which work done is maximum isobaric work?
The area under isobaric expansion is the maximum. Thus, the highest work done will be by the isobaric expansion. So, the ${w_3}$will hold the greatest value.
Which compression requires less work done?
Adiabatic process consumes lesser work of the two, because, the index of adiabatic process is n=1.4 for air and generally above 1. This means that the slope of the process curve on P-V diagram is steeper as compared to isothermal process with index n=1, thus covering less area under the curve and hence lesser work.
What is the difference between adiabatic and isothermal expansion?
It means work done by the system (expansion) in isothermal process is greater than the adiabatic process for same change in volume. In picture 2, for the same volume change area under the adiabatic compression curve is greater than the area under the isothermal curve. Consider a closed system.
Which process will do more work isothermal or isobaric?
In general, on this plot , processes of isothermal and isobaric are compared then isobaric process will do greater work. The correct answer depends upon the condition that volume is increased or decreased in process. If expansion is occurring, isothermal work is greater and if volume is decreased then isobaric work is greater.
Why does adiabatic expansion have less area under the PV curve?
This results in a greater drop in pressure for the adiabatic expansion to reach the final volume than that for the isothermal expansion, and thus less area under the p V curve and less work.
What is the difference between adiabatic compression and isothermal compression?
Although the adiabatic compression work is less negative than the isothermal compression work, the amount of work depends only on its magnitude. Hope this helps. 1. Expansion process: The image on left is for expansion where the initial conditions are P1V1.
