Convection.
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.
This transfer of heat is called convection.
Thermal energy moves in predictable patterns through conduction, convection, and radiation. Conduction is the transfer of heat through direct contact between materials, convection involves the movement of heated particles in fluids, and radiation is the transfer of heat through electromagnetic waves.
Heat energy is considered thermal energy because it is the energy associated with the random motion of particles within a substance. When particles are heated, they gain kinetic energy and vibrate more vigorously, increasing the substance's overall thermal energy. This thermal energy can be transferred between objects through conduction, convection, or radiation.
This is known as convection heat transfer. As particles in a heated substance rise, they carry heat energy with them, causing cooler particles to move in to take their place. This circulation creates a transfer of heat throughout the substance.

When a substance is heated, it gains thermal energy. This increased energy causes the substance's particles to move faster and its temperature to rise.

Heat transfer is the transition of thermal energy from a heated item to a cooler item.

Matter gains energy when it is heated due to a thermal transfer. It does not always evaporate when heated as this varies based on the specific material being heated.
This transfer of heat is called convection.
Convection, where the transfer of thermal energy it occurs by the actual movement of the heated air in a circular motion.
