Graphically show the total work done in an expansion when the state of an ideal gas is changed reversibly and isothermally from (Pi, Vi) to (Pf, Vf) . With the help of a pV plot compare the work done in the above case with that carried out against a constant external pressure Pf.
(i) Reversible work is represented by the combined areas
(ii) Work against constant pressure, Pf is represented by the area
Work (i) > Work (ii).
The Approach While Dealing With the Concept of Thermodynamics
Since the concept of Thermodynamics and the terminologies of Chemistry are a bit new to the students, they should first learn the names of different chemical components and how to write the chemical equations properly through NCERT Exemplars and Solutions books.
While writing the chemical equations, they might make some mistakes. To avoid making errors, they shoul

The Approach While Dealing With the Concept of Thermodynamics
Since the concept of Thermodynamics and the terminologies of Chemistry are a bit new to the students, they should first learn the names of different chemical components and how to write the chemical equations properly through NCERT Exemplars and Solutions books.
While writing the chemical equations, they might make some mistakes. To avoid making errors, they should practice writing the equations at home.
Solving previous years' question papers will help them to manage time and quickly analyze the answers in their minds.
Comparing their own answers with the solutions provided in the NCERT Exemplar Solutions will help them to be sure of the fact that how efficient they are at answering the questions of Chemistry. It will help them to boost their confidence as well.
Revising is extremely important when it comes to answering Chemistry questions since a lack of practice and habits of writing can make the students forget some important information that they should include in their answers. The mock papers are beneficial for them to serve this purpose
Rational thinking plays an important part in answering the questions in Chemistry. The students need to have a clear idea of the basic physical characteristics of different chemical compounds and how they will react depending on the presence of other external factors. Practicing is the only way to sharpen their thinking ability and analysis power.
