What ?em3ry said:The spacing should be zero absolute zero
How do you define "the distance between atoms"? Atoms are not billiard balls. They don't have a well defined "edge".em3ry said:The distance between atoms. Not the distance between atom centers.
So are you saying that at absolute zero, you model the atoms like billiard balls, all still, and packed together, without any gaps at the surface contacts. You hypothesise that as the material is heated, the average KE increases, the balls move about more but remain bonded, and the average gap between the balls must increase, because billiard balls are incompressible?em3ry said:The distance between atoms. Not the distance between atom centers.
The volume of a solid at absolute zero is the theoretical minimum volume that a solid can occupy when it is at the lowest possible temperature, which is 0 Kelvin or -273.15 degrees Celsius.
As temperature increases, the volume of a solid also increases due to thermal expansion. On the other hand, as temperature decreases, the volume of a solid decreases until it reaches its minimum at absolute zero.
No, the volume of a solid at absolute zero is not equal to zero. While it is at its minimum, it is not completely compressed to a point of having zero volume. It still has a finite volume, but it is the smallest possible volume for that particular solid.
The volume of a solid at absolute zero is important because it is a fundamental concept in thermodynamics and helps us understand the behavior of matter at extreme temperatures. It also has practical applications in fields such as material science and engineering.
No, the volume of a solid at absolute zero cannot be measured directly since it is a theoretical concept. However, it can be estimated through mathematical models and experiments at very low temperatures close to absolute zero.
