Heat is the transfer of thermal energy.
There is also convection, which is gas molecules gaining the heat energy, then the gas moves around, carrying the heat with it.
Electromagnetic radiation, such as visible light or radio waves, can transfer energy across vacuums. This is because electromagnetic waves do not require a medium to propagate, enabling them to travel through empty space.
Heat is transferred through thermal conduction by the vibration of atoms and molecules in a material. When a material is heated, the kinetic energy of the atoms and molecules increases, causing them to collide with neighboring particles and transfer energy. The rate of heat transfer through conduction is determined by the thermal conductivity of the material and the temperature gradient across it.
When thermal energy is transferred through a solid material, it is called conduction. This process involves the transfer of heat energy through direct contact between the particles within the solid material. The rate of conduction depends on the thermal conductivity of the material and the temperature gradient across it.
Heat transfer through a metal rod occurs primarily through conduction, where thermal energy is transferred from atom to atom within the material. The rate of heat transfer is influenced by the thermal conductivity of the metal, the temperature difference across the rod, and the cross-sectional area of the rod. Heat conduction in a metal rod follows Fourier's Law of Heat Conduction.
Moisture acts as a conductor of heat, aiding in the transfer of thermal energy across the material. The presence of moisture creates more pathways for heat to travel through the material, increasing its thermal conductivity. This leads to a higher overall thermal conductivity in materials with moisture content.
Radiation
Thermal energy is transferred on Earth's surface through three main processes: conduction (direct transfer through material contact), convection (transfer through fluid movement), and radiation (transfer through electromagnetic waves). These processes work together to distribute heat and regulate temperature across the surface of the Earth.

This process involves the transfer of heat energy through direct contact between the particles within the solid material. The rate of conduction depends on the thermal conductivity of the material and the temperature gradient across it.
The two main ways thermal energy is transferred within the climate system are through conduction, which is the transfer of heat through solids, and through convection, which is the transfer of heat through fluids like air and water. These processes play a critical role in redistributing heat across the Earth's surface and atmosphere.

Radiation is a form of energy transfer that can occur across vacuums, such as in the form of electromagnetic waves like light and heat. This is because radiation does not require a medium to propagate.
Moisture acts as a conductor of heat, aiding in the transfer of thermal energy across the material. The presence of moisture creates more pathways for heat to travel through the material, increasing its thermal conductivity. This leads to a higher overall thermal conductivity in materials with moisture content.
Thermal conductivity in a material is calculated by measuring the rate of heat transfer through the material and dividing it by the product of the material's thickness and the temperature difference across it. This calculation helps determine how well a material can conduct heat.
Radiation can carry thermal energy across a large distance because it does not require a medium, such as air or water, to transfer heat. Instead, radiation can travel through empty space in the form of electromagnetic waves, allowing it to transport heat over long distances.
