it is impossible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work

it is possible to construct an engine working on a cyclic process, whose sole purpose is to convert heat energy into work

it is impossible to construct a device which operates in a cyclic process and produces no effect other than the transfer of heat from a cold body to a hot body

none of these

It is possible to transfer heat from a body at a lower temperature to a body at a higher temperature

It is impossible to transfer heat from a body at a lower temperature to a body at a higher temperature, without the aid of an external source

Heat can be transfer itself from low temperature to high temperature

None of these

all the reversible engines have the same efficiency for a given fixed temperatures limit

all the reversible and irreversible engines have the same efficiency

irreversible engines have maximum efficiency

all the reversible engines are less efficient than irreversible engines
