Question on: JAMB Physics - 2023
Which of the following thermometers measures temperature from the thermal radiation emitted by objects?
Pyrometer thermometer
Platinum resistance thermometer
Thermocouple thermometer
Constant pressure gas thermometer
A pyrometer thermometer measures temperature from the thermal radiation emitted by objects. Pyrometers are specifically designed to measure high temperatures, and they operate based on the principle that the intensity and colour of the thermal radiation emitted by an object are related to its temperature. Pyrometers are commonly used in applications such as metalworking, industrial processes, and temperature measurement in furnaces.
