In cold countries, alcohol is preferred over mercury as a thermometer liquid because the melting point of alcohol can be lower. This ensures that alcohol remains liquid at lower temperatures, making it effective for use in cold climates where mercury ...
Thermocouples are made by two dissimilar metals. When these metals are joined at both ends, a voltage is generated when there is a temperature difference between the junctions. This voltage can be measured and used to determine the temperature.
Radiation pyrometers measure temperatures above 800°C. These instruments detect thermal radiation emitted by an object and convert it into a temperature reading. They are commonly used in high-temperature industrial processes such as metalworking, ceramics, and glass manufacturing, where temperatures exceed ...
On the Celsius scale of temperature, absolute zero temperature is -273.15°C. Absolute zero is the lowest possible temperature where particles of matter have minimal thermal motion, theoretically reaching a state of complete rest. It serves as the zero point for ...
