Today, the temperature of an object in kelvin is defined relative to the triple point of water – the point at which ice, liquid and steam exist in equilibrium. In 2018 the kelvin is to be redefined in ...

While the impact of such an achievement is not immediately obvious, the measurement could revolutionize the way we define temperature, replacing the standard method that has been used for over 50 ...

The history and physics of cooling things can be quite ... If I were to give a simple definition of temperature, I would say that it is a measure of the average motion energy of the particles ...
