In materials, conduction primarily occurs through the transfer of energy by free electrons, lattice vibrations (phonons), or through the movement of charged particles (ions) in electrolytes. In metals, free electrons carry electric charge and heat, while in insulators and semiconductors, phonon vibrations play a significant role in conducting heat.

What is conduction curent?
Conduction current refers to the flow of electric charge through a conducting material, such as a metal wire, due to the movement of free electrons. It is one of the mechanisms by which electric current is transmitted in a circuit.
How is energy transeferred?
Energy can be transferred through mechanisms such as conduction (direct contact), convection (through fluids or gases), and radiation (electromagnetic waves like light). In these processes, energy is passed from one system to another without physical particles being transferred.
How many ways does heat transfer occur?
Heat transfer occurs through three main mechanisms: conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles, convection involves the movement of fluids to transfer heat, and radiation is the transfer of heat through electromagnetic waves.
could conduction happen between two objects that were not touching?
No, conduction requires physical contact between objects to transfer heat. Without direct contact, conduction cannot occur.
How is heat transferred from one molecule to another?
Heat is transferred between molecules through three main mechanisms: conduction, convection, and radiation. In conduction, heat transfer occurs through direct physical contact between molecules. Convection involves the transfer of heat through the movement of fluids. Radiation is the transfer of heat through electromagnetic waves, without the need for a medium.
Why can't the sun's heat travel to Earth by conduction or convection?
Because both of those mechanisms take place in physical material stuff, of which there isn't any between the sun and the Earth.

Are there any other types of heat transfer?
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
How many type of heat?
There are 3 main Heat Transfer Mechanisms: Conduction, Convection and Radiation.
Is a thermal conduction a physical property?
Thermal conductivity is a Physical property
Is energy change a chemical or physical change?
Conduction of energy is a physical change.

Describe the three basic mechanisms of heat transfer?
1.Conduction or diffusionThe transfer of energy between objects that are in physical contact2.ConvectionThe transfer of energy between an object and its environment, due to fluid motion3.RadiationThe transfer of energy to or from a body by means of the emission or absorption of electromagnetic radiation

What is the term for heat transfer of direct contact?
Conduction is the term for heat transfer because of direct contact.
Is a conductor of energy a physical or chemical change?
The conductor of energy is not a physical change. The conduction of energy happens due to a chemical bonding of specific metals. A conductor of energy produces a flow of electrical charges.
