Description

Thermal Conduction

Thermal conduction is the process of heat transfer through a material. In solids, particles are closely packed, while in gases, they are far apart. Liquids have particles that are closer than gases but still allow for movement.

  1. a

    State the reason why thermal conduction is inefficient in gases.

    Aim for approximately 1 distinct marking point.
