Temperature Ocean Water, which is water specially prepared with a specified blend of hydrogen and oxygen isotopes. Absolute zero is defined as precisely and . It is the temperature at which all classical translational motion of the particles comprising matter ceases and they are at complete rest in the classical model. Quantum-mechanically, however, zero-point motion remains and has an associated energy, the zero-point energy. Matter is in its ground state, and contains no thermal energy. The triple point of water is defined as and . This definition serves the following purposes: it fixes the magnitude of the kelvin as being precisely
Planck temperature scale Planck temperature scale The Planck temperature scale is an absolute temperature scale using natural units. On this scale, 0 is absolute zero, and 1 is the Planck temperature. Quantum Theory states that the Planck temperature is the hottest possible temperature. The symbol used for this scale is "T". The freezing/melting point of water on this scale would be written 1.928 × 10"T". A way of expressing temperatures in more familiar sized units is to use centimicroyocto plank temperatures (cµy"T"). The freezing point of water is 1.928 × 10"T". By simply moving the decimal point 32 places to the right, you
