A metal spoon in a hot cup of coffee becomes warm due to conduction.

Definition

Noun: 1. The process by which heat, electricity, or sound is transmitted directly through a substance or material without any perceptible motion of the substance itself. This process involves the transfer of energy from particle to particle within the material.

Usage

• Conduction is a fundamental concept in physics and engineering. It describes a specific mode of energy transfer.
• It is typically used with the preposition "of" to specify what is being conducted (e.g., conduction of heat).
• It often appears in scientific, technical, and educational contexts.

Examples

• Metals are excellent at the conduction of electricity.
• The conduction of heat through the metal pan quickly warmed the food.
• In solids, sound travels by conduction through the vibration of molecules.
• The experiment measured the thermal conduction properties of different insulating materials.

Advanced Usage

• Electrical conduction: The movement of electrically charged particles through a medium, resulting in an electric current.
  • Copper wire is used for its high electrical conduction.
• Thermal conduction (or heat conduction): The transfer of thermal energy (heat) through a substance from a region of higher temperature to a region of lower temperature.
  • The handle remained cool due to the material's poor thermal conduction.
• To be a conductor of [heat/electricity/sound]: This phrase describes a material's ability to facilitate conduction.
  • Water is a conductor of electricity, which is why it's dangerous to use electrical devices near it.

Variants and Related Words

• Conduct (verb): To allow heat, electricity, or sound to pass through.
  • Copper conducts electricity very well.
• Conductive (adjective): Having the property of conducting something.
  • The material is highly conductive.
• Conductor (noun): A substance or object that allows the conduction of energy.
  • Metals are good conductors of heat.
• Conductivity (noun): The measure of a material's ability to conduct.
  • The engineer tested the cable's electrical conductivity.

Synonyms

• Transmission
• Transfer
• Propagation (often used for waves, like sound)

Antonyms

• Insulation
• Resistance (in the context of impeding flow)
