How are thermodynamic laws related to one another?

[QUOTE="mech-eng, post: 6797593, member: 492067"] Would you please explain how the laws of thermodynamics are related to one another? Are the laws [B]entirely independent [/B]of one another? I can see only a connection between the zeroth law and the second law. Following is the quote from my previous thread. 1. Zeroth law: The zeroth law of thermodynamics states that when two bodies have equality of temperature with a third body, they in turn have equality of temperature with each other (sonntag\borgnakke) 2. First law: The First Law states that whenever energy is converted in form, its total quantity remains unchanged ([URL="http://www.soas.ac.uk"]www.soas.ac.uk[/URL]) 3a. Second Law (Kelvin-Planck Statement): The Kelvin–Planck statement: It is impossible to construct a device that will operate in a cycle and produce no effect other than the raising of a weight and the exchange of heat with a single reservoir (sonntag\borgnakke) 3b. Second Law (Clasius Statement): It is impossible to construct a device that operates in a cycle and produces no effect other than the transfer of heat from a cooler body to a warmer body (sonntag\borgnakke) Following is the quote from my previous thread. [URL]https://www.physicsforums.com/threads/how-accurate-is-the-definition-of-heat.1045265/[/URL] So can we say that the zeroth law is the result of the second law? Is this true? Are there reason-and-result relations in laws of thermodynamics? [/QUOTE]
