According to Kelvin-Planck’s statement of second law of thermodynamics
(a) It is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work
(b) It is possible to construct an engine working on a cyclic process, whose sole purpose is to convert the heat energy into work
(c) It is impossible to construct a device which while working in a cyclic process produces no effect other than the transfer of heat from a colder body to a hotter body
(d) When two dissimilar metals are heated at one end and cooled at the other, the e.m.f. developed is proportional to the difference of their temperatures at the two end.
(e) None of the above.
