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.
