second law of thermodynamics is a kelvin-planks statement
it states that the heat cannot transfer from cold temp to
high temp without any external workdone

Answer / gurmeet.mech

Clausis statement: it is impossible to construct an engine
which will transfer the heat from low temperature sink to a
higher temerature source.

Kelvin statement: It is impossible to construct an engine
which will do any work by operating between the same
temerature sources.

Answer / sreekesh s

Answer / sornakumar

charles statement 'the engine cant design the available
heat energy fully converted into work with out loss '

region to hot region without adding work.

Answer / prasadsurendranaik

it is impossible to take energy from sink to source unless
use of externnal force

whenever you operate a heat engines between same sourse &
sink it has same efficiency

thanQ

Answer / hari prasad

It is impossible to construct a device that operates in a
cycle and produces no
effect other than the removal of heat from a body at one
temperature and the
absorption of an equal quantity of heat by a body at a
higher temperature.
