• chemical energy transforms to magnetic energy

• thermal energy transforms to electrical energy

• gravitational energy transforms to chemical energy

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

How is convection different from conduction?

• Convection can transfer heat through a vacuum, but conduction cannot

• Conduction can transfer heat through a vacuum, but convection cannot

• Convection takes place only in liquids and gases, but conduction transfers heat in solids as well

• Convection takes place only in solids, but conduction transfers heat in liquids and gases as well

Which is an example of heat transfer through radiation?

• Light from a fire shines on objects, which absorb the light and transform it into thermal energy

• A fire consumes oxygen in air to produce ash and smoke

• A fire heats a pot, which transfers heat to beans in the pot

• A fire heats the air around it, which moves out from the fire in currents of warm air
