Zeroth Law of Thermodynamics

In summary, the set average temperature for the universe is 4K and the percentage of the universe that would be habitable solely based on temperature is the liquid range of water, which is 273K-373K. The zeroth law of thermodynamics does not necessarily fit into this concept of habitability.

Is there a set average temperature for the universe? And taking into consideration our habitable temperature is x being closer to y than z. If so where does zeroth law of thermodynamics fit?

x='s Earth's surface average temperature
y='s absolute zero
z='s surface of the sun

What percentage of the universe would be habitable solely based on temperature. A link will do, I've been trolling around thermodynamic web forums and the like...-Beastcloud

Well, 4K is a pretty good answer.

By "habitable" I will assume "life as we know it". If you wish to change that, you'll need to be more specific.

And with that assumption, the answer is easy: the liquid range of water: 273K-373K. This is is known as the http://en.wikipedia.org/wiki/Goldilocks_zone#Goldilocks_phenomenon".



But I'm not sure those are the answers you were looking for...

What is the Zeroth Law of Thermodynamics?

The Zeroth Law of Thermodynamics states that if two systems are in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other. This means that if two systems have the same temperature as a third system, then they have the same temperature as each other.

What is the significance of the Zeroth Law of Thermodynamics?

The Zeroth Law of Thermodynamics is significant because it allows us to define the concept of temperature and the measurement of temperature. It also helps us understand how heat flows between systems and how thermal equilibrium is achieved.

How does the Zeroth Law of Thermodynamics relate to the First and Second Laws?

The Zeroth Law of Thermodynamics is the basis for defining temperature, which is a key concept in the First and Second Laws of Thermodynamics. It also helps us understand how energy and heat are transferred between systems in accordance with these laws.

What are some real-life applications of the Zeroth Law of Thermodynamics?

The Zeroth Law of Thermodynamics has several real-life applications, such as in the design and operation of refrigeration systems, air conditioning systems, and heat pumps. It is also used in the measurement of temperature and in the calibration of thermometers.

Can the Zeroth Law of Thermodynamics be violated?

No, the Zeroth Law of Thermodynamics is a fundamental law of nature and cannot be violated. It has been extensively tested and has been found to hold true in all known physical systems. Any apparent violations can be explained by incomplete understanding or incorrect assumptions about the systems in question.
