The si unit of temperature is kelvin
WebSep 15, 2024 · Heat and Temperature are two related terms that people may confuse often. Heat is a form of energy that is transferred between two bodies. However, Temperature is a measure of the degree of hotness or is the intensity of sensible heat. WebJun 9, 2024 · The kelvin unit was designed so that a change of 1 K corresponds to a change of 1 ∘ C. This makes sense because people were working in Celsius at the time. Kelvin just realized that the Celsius scale couldn't go down arbitrarily negative. It stopped at − …
