Question

1. a natural gas stove converts chemical energy from burning into thermal energy used to co food.

a curling iron transforms electrical energy into
○ light energy
○ electrical energy
○ mechanical energy
○ thermal energy

Explanation:

A curling iron uses electricity to produce heat for styling hair. So it transforms electrical energy into thermal (heat) energy. Light energy is for producing light (like a bulb), electrical energy is the input here, and mechanical energy involves motion/force (not the case for a curling iron's main energy output).

Answer:

Thermal energy (the option corresponding to "Thermal energy" among the choices, likely the last option: "Thermal energy")
