What does temperature mean?

Answer 1

Temperature is defined as the average total kinetic energy per particle in a system. In common terms, it means how hot or cold something is or feels, usually expressed as relative to an arbitrary point (e.g. water freezes at 0oC and this is normally called a "cold" temperature; the human body is around 37oC and this is sometimes considered "warm" or "hot"). Temperature is the measure of hotness expressed in terms of any of several arbitrary scales, such as Fahrenheit, Celsius, or Kelvin.

"Heat flows from a hotter body to a colder one and continues to do so until both are at the same temperature. Temperature is a measure of the average energy of the molecules of a body, whereas heat is a measure of the total amount of thermal energy in a body."

Answer 2

Temperature is a measurement of the average kinetic energy of the particles in a substance. It indicates how hot or cold a substance is relative to a reference point, such as the freezing or boiling point of water. Temperature is typically measured in units such as Celsius, Fahrenheit, or Kelvin.
