Answer 1

In solids, the constituent particles are very closely packed. They cannot move from one place to another, but only vibrate about their mean position. When one end of the spoon is heated, the particles at that end absorb heat energy and start vibrating more rapidly. These vibrating particles collide with the neighbouring particles and transfer a part of heat energy to them. As a result, these particles also start vibrating more rapidly. This process continues until the last particle also starts vibrating rapidly. Thus, the heat energy is transferred to the entire spoon and the object becomes hot.
