At present, in the universe is the lowest temperature of minus 273.
15 degrees Celsius.
Currently, this is a can not meet, can only be infinitely close to the lowest temperature.
Researchers have recently laser technology, based on the laser cooling technology with potassium sodium gas molecules reached five baina lates kelvin, this value is equivalent to a c one over one hundred million without money.
Zero kelvin is absolute zero, all the atomic vibration will stop, when it reaches the temperature value.
When the material is very close to 273 c.
15 degrees Celsius, there will be a interesting situation,
we can learn from the textbook, absolute zero to minus 273. 15 degrees Celsius, about 459 c. 67 degrees Fahrenheit, the vibration of the particles can produce heat, if we will stop the vibration, then not have external radiation heat. Scientists at the Massachusetts institute of technology through a new study has found that ultracold molecules in the process of near absolute zero will enter a state of strange, like the molecular magnet to absorb, before this item has not been a better explanation. MIT professor Martin Xavier l think we have very close to absolute zero, the research of molecular motion observation plays a big role.
when molecules are no longer around & other; Running & throughout; So it can be under the framework of quantum mechanics study the behavior of molecules. Absolute zero is the theory of temperature all molecular motion ceases, ideal gas enthalpy and entropy reaches the minimum at this time. Of course occur at absolute zero, the subatomic particles at the quantum level still movement. America's space agency, NASA, measuring the value of the surface by the microwave background radiation, the average temperature is about 270 c. 42 degrees, namely 454 below zero. 76 degrees Fahrenheit, haven't reached absolute zero.
stop molecules into the state need powerful laser intervention, using frequency and vibration state matching laser molecular motion control. Scientists at the Massachusetts institute of technology in the 500 degrees kelvin, but the real test is not the coldest temperature ever, 2003 is also MIT with NASA scientists conducted experiments to 0. 5 the kelvin. Observe near absolute zero process can be found unexpected like now, scientists hope to use this technology research of molecular motion, research state of all kinds of strange matter.
China laser equipment factory professional laser equipment manufacturers, products include: optical fiber laser cutting machine, fiber laser marking machine, laser engraving machine, etc.
