When the two systems in contact are at the same temperature, we say they are in thermal equilibrium. Zeroth law of thermodynamics: Defining thermal equilibrium The zeroth law of thermodynamics defines thermal equilibrium within an isolated system. The zeroth law says when two objects at thermal equilibrium are in contact, there is no net heat transfer between the objects; therefore, they are the same temperature.
Another way to state the zeroth law is to say that if two objects are both separately in thermal equilibrium with a third object, then they are in thermal equilibrium with each other. The zeroth law allows us to measure the temperature of objects. Any time we use a thermometer, we are using the zeroth law of thermodynamics.
Let's say we are measuring the temperature of a water bath.
In order to make sure the reading is accurate, we usually want to wait for the temperature reading to stay constant. We are waiting for the thermometer and the water to reach thermal equilibrium!
What is the relationship between temperature, heat, and kinetic energy?
At thermal equilibrium, the temperature of the thermometer bulb and the water bath will be the same, and there should be no net heat transfer from one object to the other assuming no other loss of heat to the surroundings.
Converting between heat and change in temperature How can we measure heat? Here are some things we know about heat so far: Learn about the differences between the two concepts in science. Test your understanding with a quiz. Definitions of Heat and Temperature Heat and temperature are two similar concepts; it's understandable to mix them up.

This is partly because scientific and everyday meanings of words aren't always the same. A person might say, 'The heat here is unbearable! But if a scientist says it, that would be a different matter. A physicist might say, 'The temperature here is unbearable! Temperature is a measure of the average movement or kinetic energy of the molecules in the substance. A higher temperature means the molecules are moving faster.
In day-to-day life, we usually use Fahrenheit or Celsius as the units of measurement, but the scientific unit is kelvin.
What is the relationship between temperature, heat, and kinetic energy? | Socratic
Comparison of the Temperature Scales Heat is the total energy that those moving molecules have. It includes both the movement kinetic energy of the molecules, and the potential energy of the molecules. The majority of heat energy on Earth originally comes from the sun, though some is a result of radioactivity in the Earth.
