Does isothermal expansion do more work than adiabatic expansion?
The amount of work done in the isothermal expansion is greater than work done in the adiabatic system for same final volume.
Why the isothermal reversible work of expansion of an ideal gas is greater than that of an adiabatic reversible expansion?
If the compression is isothermal, the temperature and, therefore, the internal energy does not increase during compression because there is heat flow out of the gas. So for the same amount of work done on the gas, there is a smaller pressure increase than in the adiabatic case.
In which case the work done is more and why isothermal compression or adiabatic compression?
Area under p-v curve gives work done. Since slope of adiabatic process is y(gamma) times isothermal process whose slope is (-p/v). Therefore area under adiabatic process is more compared with isothermal. Hence work done in adiabatic compression is more then isothermal compression.
Why is work done maximum in adiabatic process?
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 in adiabatic process is less than isothermal?
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.
Why is reversible work greater than irreversible work?
In general, energy released by a reversible process can do the maximum amount of work because less of the energy is lost as heat. A process that is done quickly (irreversibly) tends to generate turbulence and friction resulting in heat loss to the surroundings.
Is isothermal work more than adiabatic work?
Why adiabatic curve is more steeper than isothermal True or false?
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 does reversible expansion do more work?
The reversible expansion does the maximum amount of work because the gas is pushing against the maximum possible external pressure.
Why is the slope of adiabatic curve higher than isothermal curve when a gas is expanded reversibly?
γ is always greater than 1 as the specific heat at constant pressure is always greater than that at the constant volume. Hence, the slope(steepness to be exact) is more in the case of adiabatic curve by the factor of γ in comparison to isothermal curve. Most things heat up when you compress them adiabatically.
What is the difference between isothermal expansion and adiabatic expansion?
The reason is the isothermal expansion process uses the heat transferred from the surroundings to do its work, whereas for the adiabatic expansion Q = 0 and the process uses the system’s internal energy to perform its work.
What is the work done in isothermal process?
Work done in Isothermal process 1 In an isothermal process temperature remains constant. 2 Consider pressure and volume of ideal gas changes from (P 1, V 1) to (P 2, V 2 ). 3 This can be also written as W = 2.303nRT log(V 2 V 1) W = 2.303 n R T l o g ( V 2 V 1)
Why is isothermal energy more energy released than work done?
In otehr words, heat energy IS being conducted through the walls of the container. So some of the energy released by the isothermal process goes into heat conduction instead of work. So the energy released by the process is greater than the work done by the container.
What is the difference between isothermal compression and adiabatic compression?
Similarly work required by the process during isothermal compression is less than the work required by the gas during adiabatic compression. That’s why we perform intercooling of the gas between two compressor stages as a gas with less temperature requires less work than the gas at higher temperature.
