Kelvin (K): The Kelvin scale is based on absolute zero, the theoretical lowest possible temperature where particles have minimal kinetic energy. Absolute zero is 0K, and temperatures in Kelvin can never be negative.
Temperature can be measured using various instruments, including thermometers, thermistors, and thermocouples. These instruments use different principles to measure temperature, such as expansion of liquids, changes in electrical resistance, or voltage differences.
