Why absolute zero of temperature doesn't depend upon properties of substance?
In my syllabus its written "understand that there is an absolute scale of temperature that does not depend on the property of any particular substance"phinds said:I don't understand what you mean, can you clarify your question?
If you heat a piece of metal to 100 degrees how is that temperature any different than heating a piece of glass to 100 degrees, or a piece of wood ?
And by the way, "absolute zero" is not believed to be achievable in reality.

-273K is called absolute 0 temperature where there is no any kinetic energy in molecule . Practically it doesn't exist but theoretically it does . So, my question is why absolute zero temperature doesnot depend upon property of particular substance.drvrm said:do you wish to say that temperature of a body is not absolute and is defined with respect to material/substances?
do you say 50 degree of water or hydrogen... or you have scale of measurements including thermodynamic scale.
Exactly. Just as there is a scale of length that does not depend on what you are measuring.alex36 said:In my syllabus its written "understand that there is an absolute scale of temperature that does not depend on the property of any particular substance"

That was too easy ! thanks manphinds said:Exactly. Just as there is a scale of length that does not depend on what you are measuring.

Absolute zero is defined as the lowest possible temperature, at which all molecular motion ceases. This temperature is independent of substance properties because it is a fundamental physical constant that is determined by the laws of thermodynamics and the behavior of particles in a system.
No, absolute zero cannot be achieved in any substance. It is only a theoretical concept and has never been reached in a laboratory setting. The closest scientists have been able to get to absolute zero is a few billionths of a degree above it.
The Kelvin scale is based on absolute zero as its zero point, with each degree representing the same size interval as the Celsius scale. This means that absolute zero is equal to 0 Kelvin (0K) and all other temperatures in Kelvin are represented as positive numbers.
Yes, the concept of absolute zero applies to all substances equally. It is a fundamental physical constant that is not affected by the specific properties of a substance, such as its molecular structure or chemical composition.
No, absolute zero cannot be surpassed. It is the lowest possible temperature and represents the point at which all molecular motion stops. Going below absolute zero would violate the laws of thermodynamics and is not physically possible.
