The thermal speed of electrons in a conductor is typically on the order of 1,000,000 m/s. This speed represents the average velocity of electrons due to their thermal energy at a given temperature. It is important to note that individual electron velocities can vary widely within the conductor.
What else can I help you with?
Why is silver a good thermal conductor?
Silver is a good thermal conductor because it has a high density of free electrons that can easily transfer heat energy through the material. These free electrons can quickly move and transfer thermal energy, making silver an efficient conductor of heat.
A material that conducts thermal energy well is a thermal?
Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.
Why free electrons does not leave conductor?
Free electrons are bound to the conductor's lattice structure by electrostatic forces, preventing them from leaving. Additionally, the presence of positive nuclei within the lattice attracts the negative electrons, keeping them within the material. The random thermal motion of electrons within the conductor is not sufficient to overcome these forces and cause them to escape.
Why it is not possible to measure the drift speed for electron by timing their travel along the conductor?
It's difficult to accurately measure drift speed by timing electrons because individual electrons move randomly at high speeds, making it hard to track their motion. Also, electrons in a conductor have different velocities and directions, making it challenging to calculate an average drift speed. The collective drift speed of electrons in a current can be measured indirectly by observing the overall current flow in the conductor.
Is helium the best thermal conductor?
No, helium is not the best thermal conductor. Materials like silver and copper are much better conductors of heat than helium. Helium is actually a very poor conductor of heat due to its low density and lack of free electrons for heat conduction.

What 3 properties of nonmetals?
Not the best conductor of electricity. poor thermal conductor gain electrons easily hope this helps : )

Is an electric current a movement of electrons at near the speed of light?
No, electric current is the flow of electrons through a conductor, but the individual electrons do not move at near the speed of light. Instead, the speed of electron movement in a conductor is typically much slower.

Is wood thermal conductor?
Wood is a thermal insulator. It is a poor conductor of heat.
What is needed for heat to flow through a conductor?
You from concord lol, oh and its free moving electrons...
What is different hot and cold conductor?
A conductor has low electrical resistance when hot and higher electrical resistance when cold. This is due to the increased thermal agitation of electrons in the conductor when it is hot, causing higher resistance compared to when it is cold.
Is argon a conductor of thermal energy?
Argon is a poor conductor of thermal energy due to its low thermal conductivity. This is because argon is a noble gas with a simple atomic structure, where thermal energy is primarily transferred through the collisions of atoms rather than the movement of free electrons, which is typical of good conductors.
Distinguish between a heat conductor and an insulator.?
A heat conductor allows heat to flow easily through it due to the movement of free electrons, such as metals. An insulator, on the other hand, inhibits the flow of heat due to the lack of free electrons or tight bonding between atoms, such as rubber or wood.
