A laboratory thermometer is not used to measure body temperature because it has a wide range and low sensitivity, which makes it unsuitable for accurately measuring the narrow temperature range of the human body.

To measure temperatures beyond the range of a clinical thermometer, use specialized thermometers such as digital thermometers, infrared thermometers, or laboratory thermometers designed for higher or lower temperature ranges, depending on the measurement needs.
The freezing point of water, 0°C or 32°F, serves as a reference point for many temperature scales and helps calibrate thermometers.
Conduction is the transfer of heat through a solid material. It occurs when particles in the material collide, passing energy from the hotter to the cooler parts.
Heat transfer occurs through conduction, convection, and radiation. These processes involve the movement of thermal energy from a hotter area to a cooler one.
