Question

Five thermodynamic processes are illustrated below. All five processes are for the same ideal gas starting at the same initial pressure and temperature (P and T). Each of the five distinctly different processes results in different final equilibrium states. The labels on each of the diagrams are to be interpreted as follows: A = adiabatic L = linear IT = isothermal IV = is volumetric IB = isobaric Rank these processes from greatest to least on the basis of the amount of work that is done by the gas. Positive work should be ranked higher than negative work. Please carefully explain your reasoning.

Explanation / Answer

Here ,

the work done by a gas is given as the area under the curve of P-V curve of the gas process.

Now, looking at the graphs ,

area is maximum for Isobaric process

the order for area is Isobaric > Linear > isothermal > adiabatic > isovolumetic

Hence , the order for the greastest to lowest work is

Isobaric > Linear > isothermal > adiabatic > isovolumetic
