Heat's version of gossip — it only spreads if you're touching someone.

means The transfer of heat (or electricity) through a material by direct contact, as fast-moving particles jostle their slower neighbors into motion.

from From Latin conducere — 'to bring together, lead' (com- 'together' + ducere 'to lead'). The same root gives us 'conduct' and 'duct.' Scientists borrowed it in the 1600s-1700s to describe how heat or electric charge gets 'led through' a substance, particle handing energy to particle like a bucket brigade — no travel required, just contact.

speed factor
metals conduct fast because electrons carry the heat
opposite extreme
vacuum conducts nothing, no neighbors to bump into
everyday proof
metal spoon feels colder than wood, same room temp
