That sounds like a definition of "conduction" - as opposed to convection or radiation, which are other modes of heat transfer.
convection and radiation heat transfer bot occur without either object being in direct contact with each other.

Conduction involves the direct contact between two objects to transfer heat.
The type of heat transfer by direct contact is called conduction. Heat is transferred through a solid material or between two objects in direct contact with each other. This occurs as the particles in the material or objects collide and transfer energy to each other.
Conduction is the transfer of heat throgh solid objects in direct contact. The other two types of heat transfer are convection (through liquids and gases) and radiation (through gases and a vacuum).
The three principles of electric space heating are conduction, convection, and radiation. Conduction involves the transfer of heat through direct contact between objects. Convection is the transfer of heat through the movement of air or liquid. Radiation is the emission of electromagnetic waves that transfer heat energy.
Conduction, Convection, and radiation are all ways that heat can be transferred between 2 objects. Conduction is transfer by direct contact like when you cook something on the stove. Convection occurs when heat is transferred by movement like in the Earth's mantle. Radiation occurs when waves are used to transfer heat like sunlight.
Conduction.
"conduction"
Conduction: Heat transfer by direct contact, such as from an electric coil on a stove to the pot. Convection: Heat transfer though the air, such as in an oven. Radiation: Heat transfer via waves, such as from the Sun to Earth.
