The basic unit of temperature in the International System of Units (SI) is the kelvin. It has the symbol K. It has the symbol K. For everyday applications, it is often convenient to use the Celsius scale, in which 0 °C corresponds very closely to the freezing point of water and 100 °C is its boiling point at sea level. See more Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that … See more Many physical processes are related to temperature; some of them are given below: • the … See more There are various kinds of temperature scale. It may be convenient to classify them as empirically and theoretically based. Empirical … See more Temperature is one of the principal quantities in the study of thermodynamics. Formerly, the magnitude of the kelvin was defined in thermodynamic terms, but nowadays, as … See more Temperature scales need two values for definition: the point chosen as zero degrees and the magnitudes of the incremental unit of temperature. The See more The magnitude of the kelvin is now defined in terms of kinetic theory, derived from the value of the Boltzmann constant.
