The thermometer whose reading is indicated by a change in colour of its thermometric property is the?
Answer Details
The thermometer that changes color to indicate its reading is the "optical pyrometer". An optical pyrometer works by measuring the intensity of light emitted from an object being measured, and uses the color of the light to determine the temperature. As the temperature of the object increases, the color of the light changes, and the pyrometer detects this change to determine the temperature. This type of thermometer is commonly used in industrial settings to measure high temperatures, such as in furnaces or engines.
