The spelling of "absolute temperature" is influenced by its pronunciation, which is /ˈæbsəluːt ˌtɛmp(ə)rətjʊr/. The first syllable is pronounced with a short "a" sound followed by "b-s". The second syllable has a long "o" sound followed by a "l" and "u" sound. The third syllable has a short "e" sound followed by an "m-p" blend. The fourth syllable is pronounced with a short "e" sound followed by a trilled "r". The final syllable has an "er" sound followed by a consonantal "y" sound.
Absolute temperature refers to the measurement of temperature without any reference to its physical or environmental conditions. It is a scale of temperature that uses absolute zero (-273.15 degrees Celsius or 0 Kelvin) as its starting point. Absolute temperature is also known as thermodynamic temperature or Kelvin temperature.
The concept of absolute temperature is based on the behavior of molecules and atoms at very low temperatures. Absolute zero is the lowest possible temperature, at which all molecular motion ceases. According to the laws of thermodynamics, it is impossible to reach absolute zero.
In this scale, temperature is directly proportional to the average kinetic energy of the particles in a substance. As the temperature increases, the energy of the particles also increases. This scale does not consider the presence or absence of air or other factors affecting the temperature, it is the true measure of how hot or cold a substance is.
The most commonly used unit for measuring absolute temperature is the Kelvin (K). One Kelvin is equal to one degree Celsius, and the size of a Kelvin unit is the same as a Celsius unit. However, the Kelvin scale starts from absolute zero, while the Celsius scale has its zero point at the freezing point of water.
Absolute temperature is essential for scientific calculations and thermal measurements. It is commonly used in fields such as physics, chemistry, and engineering, where precise temperature measurements are crucial.

• Temperature measured from the absolute zero.

The word "absolute" originates from the Latin word "absolutus", which means "complete" or "free from restriction". The term "temperature" has its roots in the Latin word "temperatura", derived from "temperare", meaning "to moderate" or "to mix in due proportion".
When combined, "absolute temperature" refers to a measure of temperature that is not relative or comparative to any other temperature scale. It indicates a complete or total measurement of thermal energy in an object, independent of any reference point or arbitrary scale.
