24. Starting with the same initial conditions, an ideal gas expands from volume to in three different ways, the work done by the gas is if the process is purely isothermal, if purely isobaric and if purely adiabatic, then
(a)
(b)
(c)
(d)
Show Answer
Solution:
- The corresponding
graphs (also called indicator diagram) in three different processes will be as shown :
Area under the graph gives the work done by the gas.
