Question:
For an ideal gas, the work of reversible expansion under isothermal condition
can be calculated by using the expression w = – nRT ln Vf/Vi
A sample containing 1.0 mol of an ideal gas is expanded isothermally and
reversibly to ten times of its original volume, in two separate experiments.
The expansion is carried out at 300 K and 600 K respectively. Choose the
correct option.
(i) Work done at 600 K is 20 times the work done at 300 K.
(ii) Work done at 300 K is twice the work done at 600 K.
(iii) Work done at 600 K is twice the work done at 300 K.
(iv) ∆U = 0 in both cases.
Solution:
Option (iii) and (iv) are the answers.
