Question

what happens during conduction?
heat is transferred from warmer objects to cooler objects by moving fluids.
heat is transferred from warmer objects to cooler objects by direct contact.
heat is transferred from warmer objects to cooler objects through empty space.

Explanation:

Conduction is a mode of heat transfer. In conduction, heat transfer occurs due to direct contact between particles of a substance. When two objects are in direct contact, the more energetic (warmer) particles transfer some of their energy to the less energetic (cooler) particles through collisions. This process continues until thermal equilibrium is reached. The first option describes convection (heat transfer by moving fluids), and the third option describes radiation (heat transfer through empty space).

Answer:

Heat is transferred from warmer objects to cooler objects by direct contact.
