Turbine works from which cycle?

Question

1st law of thermodynamics,2nd law of thermodynamics,joul law.

Answer 1

A steam turbine operates by a process in which thermal energy is converted to mechanical energy. For the process to function, the first two  laws of Thermodynamics are employed directly and the third is added if you try to get the steam back and do it all over again in a cycle. That would be the Rankine Cycle of which the expansion through the turbine is only a part.

Answer 2

as you said those are law not cycle

turbine is one of components that are used in a cycle

all of laws are important and all of cycles have been written by laws.

cycles must be approved by laws

the major job of turbine is work transfer in cycle
