Is it possible to obtain a temperature lower than 0 K
delplace said:0 Kelvin is the limit where all subatomic particles stop moving.
Pengwuino said:Photons don't have kinetic energy
iamthegelo said:At 0 K it is assumed that there is no motion
Vanadium 50 said:That's twice this has been said. It's not correct. At 0K there is the minimum motion.
Temperature lower than 0 K is often referred to as absolute zero and is the lowest possible temperature on the Kelvin scale. It is equivalent to -273.15 degrees Celsius and is theoretically the point at which all molecular motion stops.
No, according to the laws of thermodynamics, it is not possible for temperature to be lower than 0 K. This is because 0 K represents the minimum amount of energy that a system can possess and any further decrease in temperature would result in negative energy, which is not possible.
At a temperature lower than 0 K, molecules would have no energy to move or interact with each other. This would result in a state where all matter is frozen and there is no molecular motion or any chemical reactions taking place.
While absolute zero is not attainable, temperatures close to 0 K (such as in the range of 10^-9 K) are used in scientific research for experiments involving superconductivity and quantum mechanics. These extreme temperatures allow for unique properties of matter to be observed and studied.
Temperature below 0 K is measured using the Kelvin scale, which starts at 0 K as the lowest possible temperature. This scale is based on the theoretical concept of absolute zero and is commonly used in scientific research and calculations.
