Thermometer

Description

A thermometer is an instrument used to measure temperature. It works by detecting changes in physical properties, such as the expansion of liquids, the resistance of materials, or the emission of infrared radiation. Common types of thermometers include mercury, alcohol, digital, and infrared thermometers. Mercury thermometers use mercury’s expansion in response to heat, while digital thermometers rely on electronic sensors. Thermometers are essential in a variety of fields, from medicine (measuring body temperature) to weather forecasting and industrial processes. They help ensure safety, comfort, and accuracy in temperature-related applications.
