  • Conduction: How Heat Transfers Through Direct Contact - Physics Explained
    When two objects are touching and transfer heat, it's called conduction.

    Here's a breakdown:

    * Conduction: Heat transfer through direct contact between objects of different temperatures. The hotter object transfers thermal energy to the colder object until they reach thermal equilibrium (the same temperature).

    * How it works: The atoms and molecules in the hotter object vibrate faster and collide with the atoms and molecules in the colder object, transferring energy.

    Examples:

    * Holding a hot cup of coffee: Your hand transfers heat from the cup, making it feel warm.

    * Cooking on a stove: The heat from the burner is conducted through the pot to the food inside.

    * Touching a metal spoon: The spoon quickly conducts heat from the hot liquid you're stirring.

    Factors affecting conduction:

    * Temperature difference: The greater the temperature difference, the faster the heat transfer.

    * Material properties: Some materials are better conductors of heat than others. Metals are excellent conductors, while materials like wood and plastic are poor conductors (good insulators).

    * Contact area: Larger contact areas allow for faster heat transfer.
