Old photographic flashbulbs burn magnesium metal in a reaction that causes a flash of brilliant white light. A photographer would need to take care not to suffer burned fingers when trying to replace the hot bulb.

What best identifies the energy transformation that occurs in the flashbulb?
chemical energy to electromagnetic energy and thermal energy
electromagnetic energy to chemical energy and thermal energy
chemical energy to electromagnetic energy
thermal energy to chemical energy
