Which state of matter is characterized by positively and negatively charged particles?

• solid

• liquid

• gas

A lamp that plugs into a wall socket draws energy, which flows through a thin wire in the bulb, causing it to heat up until it glows. What energy transformations are taking place?

• Chemical → light → electrical

• Mechanical → sound → light

• Thermal → solar → electrical

• Electrical → thermal → light
