May 29, 2015 · Dr. Ulrich Schneider wrote some years ago this interesting article (published by Max Planck Society):"A temperature below absolute zero – Atoms at negative absolute temperature are the hottest systems in the worldJanuary 4, 2013What is normal to most people in winter has so far been impossible in physics: a minus temperature.

Dec 4, 2004 · Absolute absolute temperature Temperature In summary, absolute temperature is a temperature that is measured in degrees Kelvin and it is related to the total kinetic energy of the atoms or molecules in a closed system.

May 8, 2023 · Only choosing a temperature scale with its origin at absolute zero will let you avoid that. That is because absolute zero is a physical thing. One aspect of how it is physical is, it's the temperature that works for the origin of the temperature in the ideal gas law. The size of the degree in these two systems is different. That does not matter.

Jul 23, 2006 · I think there is a difference between 0K and Absolute Zero, 0K describes absolute zero in terms we can understand, temperature. Which is defined as the average kinetic energy of the substance. Since kinetic energy isn't a vector it can't be logically negative.

Nov 17, 2004 · The measure of the Temperature would be each absolute height, and the measure of the heat transferred would be compared with the volume flux produced when you open the pipe's valve. Think of it, and realize that volume flux does not depend on those absolute heights, but in their difference .

Apr 13, 2016 · -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.

Oct 7, 2008 · Wald states that the temperature of a classical black hole is absolute zero, so it seems that within classical physics, gravity does not prevent absolute zero from being reached. According to Chavanis et al, some classical self-gravitating systems can come to an equilibrium state of finite density only far above absolute zero.

May 10, 2023 · At 0C the pressure in an ideal gas is not zero. It's zero at absolute zero. Which is 0K.

Sep 18, 2016 · At what absolute temperature T is the average translational kinetic energy 3/2 kT of a molecule equal to the change in potential energy calculated in part (a)? (Note: Above this temperature, thermal agitation prevents the dipoles from aligning with the electric field.) Homework Equations U = -p . E T = p X E The Attempt at a Solution [/B] I got ...

Mar 5, 2022 · In summary: In 1780, Charles calculated that the absolute temperature could be defined using the equation PV=nRT, where P is pressure, V is volume, and T is the absolute temperature. This was later refined by Lord Kelvin in 1848, who showed that the absolute temperature could be defined as the lowest temperature at which a pressure-volume curve ...
