  • ruФундаментальный принцип физики, утверждающий, что если две термодинамические системы находятся в тепловом равновесии с третьей системой, то они находятся в тепловом равновесии друг с другом. Этот закон устанавливает понятие температуры как измеримого свойства.

A fundamental principle in physics stating that if two thermodynamic systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This law establishes the concept of temperature as a measurable property.

    • The zeroth law of thermodynamics allows us to define temperature as a measurable property.
    • If system A is in equilibrium with system C, and system B is also in equilibrium with system C, then A and B are in equilibrium with each other, as per the zeroth law.
    • The zeroth law is essential for the operation of thermometers.
