10 Lines on Thermometer
- Thermometers are devices used to measure temperature in various objects and environments.
- They consist of a long narrow glass tube with a bulb at one end containing a liquid, usually mercury or alcohol.
- The liquid inside the thermometer expands or contracts with changes in temperature, causing it to rise or fall on a calibrated scale.
- Clinical thermometers are specifically designed to measure human body temperature and are commonly used in hospitals and homes.
- Laboratory thermometers are used to measure the temperature of objects other than the human body, such as in scientific experiments.
- Maximum-minimum thermometers record the highest and lowest temperatures reached in a given time period.
- Different thermometers use different temperature scales, with Celsius (°C) being the most commonly used scale.
- Digital thermometers have become popular due to their ease of use, accuracy, and safety, especially compared to traditional mercury thermometers.
- Infrared thermometers are non-contact devices that can measure temperature from a distance.
- Thermometers play a crucial role in various fields, including medicine, meteorology, cooking, and scientific research, helping us understand and monitor temperature changes in our surroundings.
