Absolute refers to something that is independent of any conditions or limitations. In physics, absolute temperature is measured from zero Kelvin, representing the lowest possible temperature. It is also used to describe quantities or values that are not relative and are unaffected by external factors or reference points.
Thermal properties of matter involve the behavior of materials in response to heat. It includes concepts like temperature heat capacity thermal expansion and specific heat. These properties determine how materials change when subjected to heat. Thermal conductivity defines how efficiently a material transfers heat. Heat transfer occurs via conduction convection and radiation.
The absolute zero is defined as the temperature at which particles theoretically stop their motion. The definition of absolute zero is 0 K on the Kelvin scale. Absolute zero equals -273.15°C or -459.67°F.
The Absolute Scale of Temperature is a temperature scale where zero is the absolute zero point. The most widely used absolute scale is the Kelvin scale, which expresses temperatures relative to absolute zero. In contrast to Celsius or Fahrenheit, the Kelvin scale does not contain negative values.
