Temperature and thermometric scales
WebThe temperature in degree Celsius is now defined as the temperature in kelvins minus 273.15, [2] meaning that a change or difference in temperature has the same value when expressed in degrees Celsius as in kelvins, and that 0 °C is equal to 273.15 K. Web1. Find out how fixed points are used in the construction of a temperature scale. 2. Find out how the resistance of a negative temperature coefficient (NTC) thermistor varies with temperature and compare this to other thermometric properties. 3. Explain why temperature scales depend on the type of thermometer being used. 4.

Empirical scales are based on the measurement of physical parameters that express the property of interest to be measured through some formal, most commonly a simple linear, functional relationship. For the measurement of temperature, the formal definition of thermal equilibrium in terms of the thermodynamic coordinate spaces of thermodynamic systems, expressed in the zeroth law of thermodynamics, provides the framework to measure temperature.
