Process Engineering Division – Instrumentation and Automation Section – Daily Question – Question from 2020-08-06: Discussion question: 197. What is temperature? Can temperature be measured directly?
Temperature is a measure of how hot or cold an object is. Temperature cannot be measured directly; it can only be determined indirectly by means of heat exchange between objects at different temperatures, as well as by the property that certain physical characteristics of objects change depending on their temperature.

Temperature is a physical quantity that indicates the degree of hotness or coldness of an object, and it cannot be measured directly.

Temperature is a physical quantity that indicates the degree of hotness or coldness of an object. At the microscopic level, it represents the intensity of the thermal motion of the molecules in the object.

Temperature is the degree of hotness or coldness measured according to some observable phenomenon (such as the expansion of a mercury column), on one of several arbitrary scales. It can be measured directly.

Temperature is a physical quantity that indicates the degree of hotness or coldness of an object; on a microscopic level, it represents the intensity of the thermal motion of the molecules in that object. Temperature can only be measured indirectly through certain properties of an object that change with temperature, and the scale used to determine the numerical value of an object’s temperature is called a temperature scale. It specifies the starting point for temperature readings (zero) and the basic unit for measuring temperature. The international unit is the thermodynamic temperature scale (K). Other temperature scales that are widely used internationally include the Fahrenheit scale (°F), the Celsius scale (°C), and the International Practical Temperature Scale. From the perspective of molecular kinetic theory, temperature is a measure of the average kinetic energy of the molecules in a substance. Temperature is a collective manifestation of the thermal motion of a large number of molecules, carrying statistical significance. For individual molecules, temperature is meaningless.
