What is the term used to describe the lowest possible temperature where molecular energy is minimal, corresponding to 0 Kelvin?

💡 Solution & Explanation

Absolute zero represents the theoretical lower limit of the thermodynamic temperature scale, corresponding to zero Kelvin or minus 273.15 degrees Celsius, where particles possess minimum vibrational energy. Molecular motion does not completely cease, but thermal energy reaches its absolute minimum. Questions on fundamental thermodynamic benchmarks frequently appear in general science sections.
