WebIn order to get to Absolute Zero, you’d need to put in an infinite amount of work. And that’s ridiculous. As you probably learned in physics or chemistry class, the temperature of a gas ... WebNow, if you let an object perform work, it's entropy will at best stay the same, while at absolute zero it is zero. So, you can't reach absolute zero this way either. Now, we can still reach absolute zero by simply putting a system in its quantum mechanical ground state. This requires having full control of all the degrees of freedom of the system.
WebJan 6, 2013 · At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale.” But now researchers have “created an atomic gas in the laboratory that nonetheless has negative Kelvin values.
