Zeroth law of thermodynamics in terms of heat

Click For Summary
SUMMARY

The zeroth law of thermodynamics establishes a foundational principle regarding thermal equilibrium and heat transfer. It states that if two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This implies that energy transfer occurs only when systems are not in thermal equilibrium, confirming that heat flows from a hotter system to a cooler one until equilibrium is reached. Thus, the zeroth law is crucial for understanding heat transfer dynamics in thermodynamic systems.

Is there any definition of the zeroth law of termodynamics using the heat concept?

And does the zeroth law imply that the only way 2 systems can transfer energy is if they're not in thermal equilibrium? If 1 system is transferring energy to another one, that means they're not in thermal equilibrium right?
