Engineering Thermodynamics
The general gas energy equation is (where Q1 - 2 = Heat supplied, dU = Change in internal energy, and W1 - 2 = Work done in heat units)

Q1 - 2 = dU + W1 - 2

Q1 - 2 = dU/W1 - 2

Q1 - 2 = dU - W1 - 2

Q1 - 2 = dU × W1 - 2

Q1 - 2 = dU + W1 - 2

Q1 - 2 = dU/W1 - 2

Q1 - 2 = dU - W1 - 2

Q1 - 2 = dU × W1 - 2

According to Kelvin-Planck’s statement of second law of thermodynamics,

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

None of these

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
