We investigate the evolution of spherically symmetric supernova remnants in
which mass loading takes place due to conductively driven evaporation of
embedded clouds. Numerical simulations reveal significant differences between
the evolution of conductively mass loaded and the ablatively mass loaded
remnants studied in Paper I. A main difference is the way in which conductive
mass loading is extinguished at fairly early times, once the interior
temperature of the remnant falls below ~10 million K. Thus, at late times
remnants that ablatively mass load are dominated by loaded mass and thermal
energy, while those that conductively mass load are dominated by swept-up mass
and kinetic energy. Simple approximations to the remnant evolution,
complementary to those in Paper I, are given.
