Explanation / Answer

the Seond Law of ThermoDynamics is shows the DISORDERNESS IN THE SYSTEM..

or

total entropy can never decrease the full time for the isolated system,

that is a system in which neither energy nor matter can enter nor left..

based on this statement we ccan describe as follows..

1000 kJ of energy are availabel from a hot thermal reservoir.

A heat engine converts 600kJ to work and rejects 500 kJ a lower temperature reservoir is violates the

second law of thermodynamics.

a 130oF cup of hot coffee is placed on the table on the table in a 75oF room. Without any work being excerted and with chemical reactions the cup of coffee heats up..

is violates the
second law of thermodynamics.

An inventor builds a device that is able to convert a specific amount of heat entirely to work in a thermodynamic cycle.

is violates the
second law of thermodynamics.
