What must be present for conduction to occur?
For conduction to occur, there must be a material with free electrons, such as a metal, to allow the flow of charge. Additionally, there must be a potential difference (voltage) across the material to drive the flow of electrons. Finally, the material should be a conductor, as insulators do not allow for the flow of charge.
What does conduction and convection have in common?
Conduction and convection are both methods of heat transfer. They both require a material medium for the transfer to occur - conduction is through direct contact between materials, while convection involves the movement of fluids.
What is the speed of conduction?
The speed of conduction depends on the type of material and the conditions it is in. For example, in a metal, conduction can be as fast as the speed of sound in that material. In general, conduction is slower than the speed of light.
When conduction occurs between two objects do the two objects need to be touching?
No, conduction can occur between objects without them needing to be in direct contact. Heat conduction can happen through a material medium or in the form of radiation, where energy is transferred through electromagnetic waves.
What are the main factys of conduction?
Thermal conduction is the transfer of heat energy through particles in contact with one another. Because heat energy is essentially kinetic energy, the particle with more kinetic energy collides with the particle with less kinetic energy, speeding it up and therefore causing it to absorb some of the heat energy from the first particle.
What is sentence for conduction?
Copper is good for electricity conduction.The entire rod became hot by conduction.

What does conduction look like?
Conduction is a phenomenon not a material.

What is the result of conduction?
Conduction is the transfer of heat through a material without any movement of the material itself. It leads to the flow of heat from hotter regions to cooler regions within the material. The result of conduction is the equalization of temperatures in the material.

How conduction can be controlled?
Conduction can be controlled by altering the material's thermal conductivity, adjusting the temperature difference across the material, or changing the thickness of the material. Insulating materials, like foam or fiberglass, can reduce conduction by limiting the flow of heat through a material. Increasing the thickness of the material can also increase resistance to heat transfer through conduction.
How does conduction worrk?
Conduction can only occur in solids. Good conductors are metal, for example. In conduction, there is a heat source. The heat will heat up one part of the solid. As a result, the particles vibrate voilently. Then, the vibrating particles will make particles next to them vibrate and so on...
Heat transfer from one material to another by direct contact?
Conduction!
What is some false statements about conduction?
Conduction requires a medium to transfer heat (false - conduction can occur in solids, liquids, and gases). Only metals can conduct heat (false - materials like ceramics and glass can also conduct heat). Conduction only occurs at a constant rate (false - the rate of conduction can vary depending on factors like temperature and material properties).
