S8P2d A metal spoon is placed in a pot of boiling water. Why does the spoon become hot over time?

• Currents of hot matter travel up the spoon from the water

• Light shining on the spoon causes it to become as hot as the water

• Particles in the water collide with particles in the spoon, which then strike other particles in the spoon, transferring energy

• Microwaves emitted by the hot water are absorbed by the spoon and transformed into thermal energy
