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.
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.
The Kelvin scale is an absolute temperature scale starting at absolute zero (0 K). It is commonly used in scientific research and calculations.
The Celsius scale is a temperature scale where water freezes at 0°C and boils at 100°C. It is commonly used in most countries around the world.
Temperature is measured using thermometers, which can be liquid-in-glass, digital, or infrared. These devices detect temperature by measuring changes in a substance, such as mercury or alcohol, or using sensors.
