The transfer of heat from one place to another by the movement of heated material is called convection. This process occurs in fluids and gases where warmer, less dense material rises, and cooler, denser material sinks, creating a continuous circulation pattern that transfers heat.
Material with low thermal conductivity.
An example of thermal energy being transferred from one material to another is when a hot iron is placed on a piece of fabric to press it. The thermal energy from the hot iron transfers to the fabric, causing the fabric to become warm and smooth.
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.
The process by which thermal energy is transferred through electromagnetic waves is called radiation.
Heat is transferred by conduction through direct contact between objects or substances. The key mechanisms involved in this process are the vibration of atoms or molecules in the material, which causes the transfer of thermal energy from one particle to another. This transfer continues until a thermal equilibrium is reached, where the temperatures of the objects are equalized.

Thermal conduction is the transfer of heat through a material by the collision of molecules. It occurs in solids, liquids, and gases and is governed by the material's thermal conductivity and temperature difference.
By the process of Radiation
Heat is transferred through solid rock via conduction, where thermal energy is transferred from one particle to another by direct contact. This process occurs when particles vibrate against each other, passing on heat energy. As a result, heat is conducted through the solid rock, spreading the thermal energy throughout the material.
The thermal conduction of water is much greater than that of wool.
Conduction is the main process that transfers thermal energy through the metal saucepan. Heat is transferred from the heat source to the metal pan through direct contact of particles within the material.
Thermal energy is transferred through conduction (direct contact), convection (through liquids or gases), or radiation (through electromagnetic waves). In conduction, heat is transferred from one molecule to another through direct contact. In convection, heated material rises and cooler material sinks, creating a cycle of energy transfer. Radiation transfers energy through electromagnetic waves that do not require a medium to travel through.
In a conductor, thermal energy is transferred through the process of conduction. This occurs as the particles of the conductor vibrate and collide with neighboring particles, transferring energy along the material. The rate of thermal energy transfer depends on factors such as the material's conductivity and temperature difference.
