Conduction is the transfer of heat through direct contact between particles of a substance. It occurs due to the collision of molecules transferring kinetic energy from warmer to cooler regions. Materials that are good conductors, like metals, allow heat to pass through easily, whereas materials with poor conductivity, like air or wood, are more insulating.
What else can I help you with?
What unit describes the difference in conduction?
Thermal conductivity is the unit that describes the difference in conduction. It is typically measured in watts per meter-kelvin (W/mK) and indicates how well a material conducts heat.
What process describes the transfer of heat directly by contact?
Conduction is the process that describes the transfer of heat directly by contact. It occurs through the collision of molecules within a substance or between two substances in contact.
What process describes the transfer of heat through matter by molecule or activity?
Conduction is the process that describes the transfer of heat through matter by molecule activity. In conduction, heat is transferred from a region of higher temperature to a region of lower temperature as a result of direct interaction between the molecules of the material.
Which unit describes the difference in conduction between the wires?
The unit that describes the difference in conduction between wires is typically the electrical conductivity or resistivity, which is measured in Siemens per meter or Ohm meters, respectively. This value indicates how well a material conducts electricity, with higher values indicating better conduction and lower values indicating higher resistance to the flow of electricity.
What do you call when a heat moves along an object?
That describes "conduction," rather than convection and radiation.
Does conduction produce heat?
no, conduction describes how the heat is transported not how it is generated. With conduction, a heat source is still needed.
Conduction along a myelinated axon is called?
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.

If One wire in a circuit is replaced by a wire that conducts less electricity which unit describes the difference in conduction between the wires?
ohms
What does insulators mean?
Something that keeps heat in.AnswerIn the electrical sense, it describes a material with insufficient mobile charge carriers available to support conduction.
Which process describes how most of the engine's heat is transferred to the coolant?
Conduction. The heat from the engine block transfers to the coolant inside the galleries by means of conduction. The coolant then has to be moved, to stop it boiling. In early simple engines, this movement was by Convection. In modern engines it is pumped.

What describes the process of heat conduction?
Heat conduction is the transfer of thermal energy between neighboring molecules in a material due to a temperature difference. This process occurs by direct contact between molecules, with energy moving from higher temperature areas to lower temperature areas until there is thermal equilibrium. Heat conduction is governed by the material's thermal conductivity and the temperature gradient.
What is the Thermal conductivity of air?
The thermal conductivity of air is approximately 0.0257 W/(m*K) at room temperature. It describes the ability of air to transfer heat through conduction.
