ANATOMY

Detailed explanation-1: -A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.

Detailed explanation-2: -Temperature is measured through thermometers according to well-defined scales of measurement, which use pre-defined reference points to help compare quantities. Kelvin, Celsius, and Fahrenheit scales are the three most common temperature scales used.

Detailed explanation-3: -Digital thermometers can be considered advanced thermometers used for measuring body temperature.

Detailed explanation-4: -Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow-i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature).
