Answer 1

Explanation:

Conduction is the primary mode of heat transfer in solid materials. When a solid is heated, the vibrations of the particles at the heated end are increased. These particles collide with each other while vibrating and transfer the heat to the slow moving neighbouring particles. They in turn begin to vibrate faster and transfer heat to their neighbours. Thus, although the particles remain in their own place, heat is transferred by the vibrating particles through conduction
