    Undergrad Is there an equation to prove the Zeroth law of thermodynamics?

    zeroth law is a practical observation that is fundamental to many process.many phenomenon can ber proved by the pre- assumption of zeroth law.just as all the gravitational phenomena can be explained if we assume gravitational force is directly proportional to the masses of the bodies and...
