Answer:
Concept:
A thermometer is a device that measures temperature or the difference between two temperatures. A thermometer has two main components: a temperature sensor that changes when the temperature changes (e.g., the bulb of a mercury-in-glass temperature sensor or the pyrometric sensor in an infrared thermometer) and a means of trying to translate this change into a numerical value (e.g., the visible scale marked on a mercury-in-glass temperature sensor or the digital readout on an infrared model). In engineering, as well as meteorology, medicine, and scientific research, thermometers are often used to monitor processes.
Given:
In order to get reliable readings, which of the following categories of thermometers must be in thermodynamic equilibrium inside the object being measured?
1. a bimetallic strip.
2. a resistance thermometer.
3. a temporal artery thermometer.
4. both 1 nd 2.
5. all thermometers.

Answer:
The correct option is option(4)
a welded strip made up of two metals with different kernels of expansion that buckles when heated. To transform a change in temperature into mechanical displacement, a bimetallic strip is used. The strip is made up of two metal strips that expand at different speeds as they are heated. Resistance thermometers, often known as temperature measurement detectors, are temperature sensors. A length of thin wire is wrapped around a high - temperature ceramic or glass core in many RTD components, but different structures are also employed.
