What is an international scale of temperature?
The International Temperature Scale (ITS) is a system of defining and measuring temperature. It is used by scientists and engineers around the world to ensure that temperature measurements are accurate and consistent.
The ITS is based on a set of reference points, which are temperatures that have been precisely defined. These reference points are used to calibrate thermometers and other temperature-measuring devices.
The ITS is updated periodically to reflect new scientific knowledge and technological advances. The current version of the ITS is the International Temperature Scale of 1990 (ITS-90).
The ITS-90 has 16 reference points, which cover the temperature range from 0.65 K to 1357.77 K. The reference points are chosen to represent a variety of physical phenomena, including the phase transitions of water, the vaporization of metals, and the emission of blackbody radiation.
The ITS-90 is a complex system, but it is essential for ensuring the accuracy and consistency of temperature measurements. It is used in a wide variety of applications, including:
- Calibrating thermometers
- Measuring the temperature of industrial processes
- Studying the properties of materials at extreme temperatures
- Conducting climate research
The ITS is a valuable tool for scientists and engineers around the world. It helps to ensure that temperature measurements are accurate and consistent, which is essential for many important applications.
