False statement regarding second law of thermodynamics is

It is impossible to construct a machine working in cycles which transforms heat from a lower temperature region to higher temperature region without intervention of any external agency.

Heat cannot flow from a colder body to a hotter body on its own

For any spontaneous process taking place in an isolated system `DeltaS lt O`

All spontaneous processes are thermodynamically irreversible & entropy of the system increases in all spontaneous processes.

False statement regarding second law of themodynamics

It is imposible to construct a mackine working in cycles which transforms heat from a lower temperature region to higher temperature region without intervention of any ecternal agency.

Heat cannot flow from a colder body to a hotter body on its own

Any spontaneous process taking place in isolated system, `Delta S lt O `

All spontaneous processes are thermodynamically irreversible and entropy of the system increases in all spontaneous processes.

The incorrect statment according to second law of thermodynamics is

Heat cannot flow from colder body to a hotter body of its own

All spontaneous processes are themo dynamically irreversible

Heat can be converted into work completely without casusing some permanent change in the system (or) surroundings

Perpetual motion machine of second kind is not possible

The incorrect statement according to second law of themodynamics is

Heat cannot flow from colder body to a hotter body of its own

All spontaneous processes are thermody-namically irreversible

Heat can be converted into work completely without causing some permanent change in the system (or) surroundings
