The freezing point of water, 0°C or 32°F, serves as a reference point for many temperature scales and helps calibrate thermometers.
Thermal equilibrium is the state in which two objects in contact no longer exchange heat because they have reached the same temperature.
Metal feels colder than wood at the same temperature because metal conducts heat away from your skin faster than wood, creating the sensation of coldness.
The rate of heat transfer is affected by the temperature difference between objects, the material’s thermal conductivity, the surface area, and the nature of the surrounding medium.
Heat is the total energy of all particles in a substance, while temperature is the average kinetic energy of those particles. Heat depends on mass, while temperature does not.
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.
