What is the scientific field focused on temperature measurement?

1. Thermodynamics

2. Thermometry

3. Heat Transfer

4. Calorimetry

The correct answer is: Thermometry

The scientific field that focuses specifically on temperature measurement is thermometry. This discipline encompasses various techniques and instruments used to assess temperature accurately. It includes the study of thermometers and the principles behind their operation, covering both the calibration of temperature measuring devices and the theory behind temperature measurement itself. While thermodynamics, heat transfer, and calorimetry are closely related scientific fields, they address different aspects of temperature and thermal phenomena. Thermodynamics studies the relationships between heat, work, temperature, and energy. Heat transfer, on the other hand, deals with the movement of thermal energy from one physical system to another. Calorimetry measures the heat transferred during chemical reactions or physical changes, but it is not primarily focused on measuring temperature itself. Therefore, thermometry is the correct choice as it solely pertains to the measurement of temperature.
