An electrical wire is brought near several objects: a tennis ball, iron filings, a plastic spoon, and glass marbles. if an electrical switch is flipped, allowing current to flow through the wire, which object will most likely respond?

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
