Heat Energy Travels Through Solids By Conduction. That is how heat is transferred particle by particle. Radio waves pass through the walls of your home to reach the antenna on your stereo.

Conduction
Conduction from www.slideshare.net

Contact is mandatory to make conduction happen. That happens because the molecules hit each other, and the faster moving molecules in the hot object spread that energy into the cooler object. By the temperature drop δt along the distance δx ( fourier’s law ):

Conduction

The other two ways heat moves around are radiation and convection. This is called conduction of heat. Metals are particularly good conductors because they also have a 'sea' of freely moving electrons ('delocalised electrons') that collide with the fixed metal atoms, transferring kinetic energy. Metal is a good conduction of heat.
