A: Work done in an irreversible isothermal process at constant volume is zero.
R: Work is assigned negative sign during expansion and is assigned positive sign during compression.
R: Work is assigned negative sign during expansion and is assigned positive sign during compression.
View answer and explanation
Correct option: B
If both A and R are correct, but R is not the correct explanation of A
Option B is correct. Assertion is correct because at constant volume, no work is done. Reason is also correct about the sign convention for work, but it doesn't explain the assertion.
