What does conduction mean and how does it happen?

When vibrating particles transfer energy to other particles, this happens mostly in solids. Energy is transferred to an object by heating which is the thermal store of an object. This energy is then shared to the kinetic energy stores of the particles which causes them to vibrate and collide, also transferring energy. This is conduction. This continues throughout the object until it reaches the other side. The remaining energy is then transferred to its surroundings.
