Accurate temperature measurement is crucial for safety, health, scientific research, and industrial processes. It ensures proper functioning, safety, and quality in various applications.
Radiation is the transfer of heat through electromagnetic waves. It doesn’t require a medium, meaning heat can travel through a vacuum, like from the Sun to Earth.
Conduction is the transfer of heat through a solid material. It occurs when particles in the material collide, passing energy from the hotter to the cooler parts.
Heat transfer occurs through conduction, convection, and radiation. These processes involve the movement of thermal energy from a hotter area to a cooler one.
Specific heat capacity is the amount of heat required to raise the temperature of 1 kilogram of a substance by 1°C. It varies for different materials.
The boiling point of water is 100°C or 212°F at standard atmospheric pressure. It is used as a reference point in temperature scales and calibrating thermometers.
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.
