c) Ratio of adiabatic heat to macroscopic variables

d) Ratio of macroscopic variables to adiabatic heat

Answer 2

(A) Ratio of reversible transfer of heat to absolute temperature

Explanation:

• This relationship expressed in increments of entropy which is to the ratio of incremental heat transfer divided through temperature, which became determined to differ withinside the thermodynamic cycle however in the end go back to the same value on the end of every cycle .
• By the Clausius definition, if an quantity of heat Q flows right into a large heat reservoir at temperature T above absolute zero, then the entropy gets increased is ΔS = Q/T.
• This equation efficiently offers an alternate definition of temperature that has the same opinion with the same old definition.

Answer is Option (A)
