A clinical thermometer is a device used to measure body temperature. It typically has a narrow temperature range and can be digital or liquid-in-glass.
Bridges have expansion joints to allow for thermal expansion and contraction. These joints prevent damage by accommodating changes in the length of the bridge due to temperature variations.
Thermal expansion is the increase in the volume of a substance when its temperature rises. This occurs because particles move faster and spread apart as they gain kinetic energy.
Temperature is a key factor in weather forecasting. It influences weather patterns, such as precipitation and wind, and helps meteorologists predict daily weather conditions and long-term climate trends.
Infrared thermometers work by detecting infrared radiation emitted by an object. They use sensors to convert this radiation into an electrical signal, which is then displayed as a temperature reading.
An infrared thermometer measures temperature by detecting infrared radiation emitted by objects. It allows non-contact temperature measurement, making it useful for both industrial and medical purposes.
Digital thermometers use electronic sensors to measure temperature and display the reading on a digital screen. They are fast, accurate, and commonly used in medical, industrial, and household applications.
The Kelvin scale is important in science because it starts at absolute zero, providing a direct measure of thermal energy. It is used in scientific calculations and studies involving temperature.
Mercury thermometers are being phased out due to the toxicity of mercury. If broken, mercury can pose serious health and environmental risks.
