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 else can I help you with?
Why must substances be touching in order for conduction occur?
Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
Why does conduction not occurs at a perfect vacuum?
Conduction requires the presence of particles that can transfer energy, such as electrons or molecules. In a perfect vacuum, there are no particles present to serve as conductors of heat or electricity, so conduction cannot occur.
Which two conditions must exist in order for radiation to occur?
Radiation occurs when an object has excess energy that needs to be released and there is no conducting medium present for conduction or convection to transfer the energy. Additionally, the object emitting radiation must be at a higher temperature than its surroundings.
Is conduction occur in fluid?
Yes, conduction can occur in fluids. In fluids, conduction takes place through molecular collisions, where heat is transferred from molecule to molecule. However, conduction is typically less efficient in fluids compared to solids due to the free movement of molecules in fluids.
In order for heat to be transferred between two objects by conduction?
the objects must be in physical contact with each other, and there must be a temperature difference between them. Heat will flow from the object with a higher temperature to the one with a lower temperature until thermal equilibrium is reached.

Because, conduction is the transfer of heat flow fro one object to another. So that means they must touch to make conduction occur.
What gas must be present for a combustion reaction to occur?
Oxygen gas must be present for a combustion reaction to occur.
What must be present for to erosion to occur?
a transporting agent, such as water must be present
What must be present for metamorphism to occur?
The changes to the rock must occur in solid form.
Why does conduction not occurs at a perfect vacuum?
Conduction requires the presence of particles that can transfer energy, such as electrons or molecules. In a perfect vacuum, there are no particles present to serve as conductors of heat or electricity, so conduction cannot occur.
Why must substance be touching in order for conduction to occur?
Conduction occurs when heat is transferred through direct contact between substances. When substances are in contact, their particles vibrate and transfer thermal energy from one to the other. Without contact, there is no medium for the heat to pass through, so conduction cannot occur.

Which two substances must be present for an iron object to rust?
For the oxidation of iron to occur, that is for ferric oxide to form, there must be oxygen present. There must also be water present.
