Zeroth law of thermodynamics

from class:

College Physics I – Introduction

Definition

The zeroth law of thermodynamics states that if two systems are each in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This principle allows for the definition of temperature.

congrats on reading the definition of zeroth law of thermodynamics. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. The zeroth law establishes the concept of temperature as a fundamental and measurable property.
  2. It forms the basis for the construction of thermometers.
  3. Thermal equilibrium means no net heat flow between systems.
  4. The zeroth law is crucial for defining what it means for two bodies to have the same temperature.
  5. It enables the use of empirical temperature scales, like Celsius and Fahrenheit.
