But ΔU = αnRΔT, so, W on 1.45 x 104 J The long way: Recall that for the isothermal process the work done on the gas was 8850 J. The work done on the gas is greater in the adiabatic process. Incidentally, the derivation of the adiabatic formulas is as follows: For small changes in T and V, the first law (ΔU = -W ...

WebAn adiabatic process is a process that takes place in such a way that no heat can enter or leave a system. This means that so the work done by the system is equal to the loss in internal energy: Therefore if the gas does work, the internal energy decreases and the temperature falls. WebMar 18, 2016 · The most extreme form of an irreversible isothermal expansion is the adiabatic isothermal expansion of an ideal gas into vacuum. In this case no pressure-volume work is done, so in the PV diagram pressure first drops to zero, then volume increases to the final volume, and the pressure increases to the final value. The area …
