#### Measurement of Temperature and Units of Thermometers A thermometer is an instrument used to measure temperature. It consists of a temperature sensor and a scale that indicates the temperature reading. The most commonly used unit for measuring temperature is the degree Celsius (°C). However, other units such as Fahrenheit (°F) and Kelvin (K) are also used in different regions and scientific applications. **The degree Celsius (°C)** is the unit of temperature measurement used in most countries around the world. It is based on the Celsius scale, where 0°C represents the freezing point of water and 100°C represents the boiling point of water at sea level. **The degree Fahrenheit (°F)** is primarily used in the United States and a few other countries. It is based on the Fahrenheit scale, where 32°F represents the freezing point of water and 212°F represents the boiling point of water at sea level. **The Kelvin (K)** is the unit of temperature used in scientific and engineering applications. It is based on the Kelvin scale, where 0 K represents absolute zero, the lowest possible temperature. The Kelvin scale is an absolute temperature scale, meaning it does not use negative values. Thermometers can be classified into various types based on the principles they use to measure temperature. Some common types of thermometers include: 1. **Mercury-in-glass thermometer**: This type of thermometer uses a glass tube filled with mercury. As the temperature changes, the mercury expands or contracts, causing the level of mercury in the tube to rise or fall. The temperature is read by observing the height of the mercury column on the scale. 2. **Digital thermometer**: Digital thermometers use electronic sensors to measure temperature. They provide a digital display of the temperature reading and are commonly used in medical and household applications. 3. **Infrared thermometer**: Infrared thermometers measure temperature without direct contact. They detect the infrared radiation emitted by an object and convert it into a temperature reading. Infrared thermometers are often used in industrial and medical settings. 4. **Bimetallic thermometer**: Bimetallic thermometers consist of two different metals bonded together. As the temperature changes, the metals expand or contract at different rates, causing the bimetallic strip to bend. The bending of the strip is used to indicate the temperature on a scale. It's important to note that the accuracy and precision of temperature measurements depend on the type of thermometer used and the calibration of the instrument.
