The process in which the work done is the highest.
Answer to Problem 1OQ
Option (b) adiabatic
Explanation of Solution
The ideal gas is compressed to half of its initial volume by isothermal, adiabatic, isobaric processes.
In PV diagram of a process, the area under the curve is equal to the work done by the process. In case of isobaric process the initial and final pressure is same. so the curve will be a straight line parallel to the volume axis.
Write the formula for the final pressure in isothermal process.
Here,
Write the formula for the final pressure in adiabatic process.
Here,
The figure below shows the PV diagram of the three process.
The work done in isobaric process is the area under the curve
Thus the work done is the highest in case of adiabatic process. Thus option (b) is correct.
Conclusion:
The work done is the highest in case of adiabatic process. Thus option (b) is correct.
The work done in isothermal process is less than adiabatic process. Thus option (a) is incorrect.
The work done in isobaric process is less than adiabatic process. Thus option (c) is incorrect.
The work done depends on the process. Thus option (d) is incorrect.
