Energy Quiz

What type of energy transformation occurs, when a hawk eats a mouse and then uses the energy from the mouse to fly?

• mechanical energy to chemical energy

• thermal energy to mechanical energy

• chemical energy to mechanical energy

• mechanical energy to thermal energy

When a car burns gasoline it creates hot air to move the pistons in the engine, which causes the car to move. What energy transformation occur from the fuel to the movement of a car?

• thermal energy to mechanical energy

• thermal energy to chemical energy to mechanical energy

• chemical energy to thermal energy to mechanical energy

• chemical energy to electrical energy

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

• chemical → light → electrical
• mechanical → sound → light
• thermal → solar → electrical
• electrical → thermal → light

When water falls through a dam and turns a turbine connected to a generator, electricity is produced. This electricity is often used to light our homes and offices. Which of the following shows the energy transformations that occurs?

• electrical → light → mechanical
• chemical → mechanical → electrical
• mechanical → chemical → light
• mechanical → electrical → light
