Such absolute temperature is independent of the properties of particular The T 1/ T 2 is defined equal to Q 1/ Q 2. If Q 1 is the heat received at the higher temperature T 1, and Q 2 the heat lost at the lower temperature T 2,

On a Carnot cycle between two temperatures T 1 and T 2. Is not arbitrary it is defined with an ideal reversible heat engine working The absolute temperature scale, unlike the other temperature scales, Absolute zero corresponds to -273° on the Celsius Zero is assigned to absolute zero – the lowest possible temperature. Scientists also used the kelvin scale, named after the British scientist Is through the formula: degrees Celsius = 5/9 × (degrees Fahrenheit - 32). Conversion to the Fahrenheit scale from Celsius This scale, the value 32 is assigned to the freezing point of water andĢ12 to its boiling point. The United States uses the Fahrenheit scale to express temperatures. On the Celsius scale, zero is assigned to the temperature at which water freezes, and 100 is given to the boiling point of water. In most laboratory work, temperature is expressed in degrees Celsius, namedĪfter the eighteenth century Swedish astronomer Anders Celsius. Is expressed by a number that corresponds to the degree of hotness on aĬhosen scale: Celsius (☌), Fahrenheit (☏), or kelvin (K) and is measured quantitatively by thermometers. It is a measure of the average kineticĮnergy of the molecules or atoms in an object. Temperature is the quantity that tells how warm or cold an object is with respect to some
