Engineering Thermodynamics
A mixture of gas expands from 0.03 m3 to 0.06 m3 at a constant pressure of 1 MPa and absorbs 84 kJ of heat during the process. The change in internal energy of the mixture is
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
