Question
Assertion : The isothermal curves intersect each other at a certain point.
Reason : The isothermal change takes place slowly, so the isothermal curves have very little slope.
✓

Answer

(e) As isothermal processes are very slow and so the different isothermal curveshavedifferent slopes so they cannot intersect each other.
