Question

what is the definition of conduction

movement of particles to spread out when the kinetic energy increases

transfer of thermal energy by direct contact of two objects or particles of matter

the process of thermal energy transfer by electromagnetic waves

a measure of the average kinetic energy of an objects particles

Explanation:

Conduction is a mode of heat transfer. It occurs when there is direct contact between two objects or substances. In conduction, thermal energy (heat) moves from the region of higher temperature to the region of lower temperature through the collision of particles. For example, when you touch a hot metal rod, heat is conducted from the rod to your hand as the particles in the rod (which have higher kinetic energy due to higher temperature) collide with the particles in your skin.

Answer:

Transfer of thermal energy by direct contact of two objects or particles of matter.
