Energy Transformation Flashcards
A lamp that plugs into a wall socket draws energy that flows through a thin wire in the bulb, causing it to glow. What energy transformations are taking place?
electrical → thermal → light
Which type of energy transformation occurs when a flashlight shines?
chemical → electrical → light
Which of the following best describes the energy transformations that occur when a flashlight that runs on batteries is turned on?
chemical → electrical → light
Which of these is an example of light energy being transformed into chemical energy?
A plant makes sugar in the sunlight.
Which kind of energy change occurs when a candle is burning?
Chemical to light.
