Detailed Solution

Concept: A measurement of temperature is how hot or cold a body is. It describes the typical kinetic energy of a substance's molecules. The substance's molecules begin to move more quickly as the temperature rises, and more slowly as the temperature falls. When a substance absorbs heat, the temperature rises; conversely, when a substance releases heat, the temperature falls. Since absolute zero is the lowest temperature possible, it is also the temperature at which molecules have no average kinetic energy. This indicates that the molecules' mobility stops and they become stationary. On various scales, the absolute zero temperature is variable, foris K on Kelvin scale, −273.15 ∘C ∘C on Celsius scale and −460 F on Fahrenheit scale.
Hence, the correct answer is option 2.
