The illustration at right shows an example of energy changing forms. Which changes in energy form are illustrated in the diagram?
electrical to sound to light and mechanical
sound to mechanical to light and electrical
mechanical to light to sound and electrical
light to electrical to mechanical and sound
The image shows a ringing bell inside a vacuum jar. As air is pumped from the vacuum jar, the sound level of the ringing bell will decrease until it can no longer be heard. This happens because air must be present in the jar in order for
sound to be transferred
electricity to flow through the wires
the rubber to seal the jar
the bell clanger to vibrate
The diagram shows a pinwheel rotating above a lit candle. The arrows indicate the direction of air flow. Which energy transformation is best shown in this diagram?
heat to mechanical
sound to heat
mechanical to light
heat to sound
In the diagram a boiler heats water, which moves a turbine. Heat moves through the water in the boiler through
radiation
convection
conduction
