Complete the energy transformation sentence below for a flashlight.

The battery provides​ (a)   which becomes ​ ​ (b)   that turns into ​ (c)   .

• Chemical Energy
• Electrical Energy
• Radiant Energy and Thermal Energy
• Chemical Energy and Nuclear Energy

• Nuclear Energy

• Radiant Energy

• Motion Energy

• Gravitational Energy

• Sound Energy

• Radiant Energy and Motion Energy

Answer explanation

In a flashlight, chemical energy from the batteries is converted to electrical energy, which then transforms into radiant energy (light) and thermal energy (heat). Thus, the correct sequence is: Chemical Energy, Electrical Energy, Radiant Energy and Thermal Energy.

Complete the energy transformation sentence below for a gas powered lawn mower.

Gasoline provides ​ (a)   which turns into ​ (b)   when the lawn mower is being used. ​

• Electrical Energy

• Nuclear Energy

• Radiant Energy

• Motion Energy, Thermal Energy, and Sound Energy
• Gravitational Energy

• Chemical Energy
• Motion Energy, Sound Energy, and Chemical Energy

• Motion Energy, Thermal Energy, and Nuclear Energy

• Motion Energy, Elastic Energy, and Radiant Energy

Answer explanation

In a gas-powered lawn mower, chemical energy from the fuel is transformed into motion energy (for movement), thermal energy (from engine heat), and sound energy (from the engine noise). Thus, the correct completion is 'Chemical Energy turns into Motion Energy, Thermal Energy, and Sound Energy.'

Complete the energy transformation sentence below for a desktop computer that is plugged into the wall.

(a)   turns into ​ (b)   . ​

• Electrical Energy
• Nuclear Energy

• Radiant Energy

• Motion , Radiant, Thermal, and Sound Energy
• Gravitational Energy

• Chemical Energy

• Motion, Sound, Thermal, and Chemical Energy

• Motion, Thermal, Elastic, and Nuclear Energy

• Motion, Gravitational, Sound, and Radiant Energy

Answer explanation

A desktop computer transforms Electrical Energy into Motion, Radiant, Thermal, and Sound Energy as it operates. The fan shows motion energy, the monitor provides radiant energy, the speakers create sound energy, and thermal (heat) energy is created by many parts of a computer.

Complete the energy transformation sentence below for a lava lamp.

(a)   turns into ​ (b)   . ​

• Electrical Energy
• Nuclear Energy

• Radiant Energy

• Motion , Radiant, and Thermal Energy
• Gravitational Energy

• Chemical Energy

• Motion, Sound, and Thermal Energy

• Motion, Thermal, and Elastic Energy

• Motion, Gravitational, and Radiant Energy

Answer explanation

In a lava lamp, electrical energy heats the wax, causing it to expand and rise (motion). Radiant energy and thermal energy is created by the light bulb, completing the energy transformation.

Complete the energy transformation sentence below for a refrigerator.

(a)   turns into ​ (b)   . ​

• Electrical Energy
• Nuclear Energy

• Radiant Energy

• Motion , Radiant, Sound, and Thermal Energy
• Gravitational Energy

• Chemical Energy

• Motion, Sound, Chemical, and Thermal Energy

• Motion, Thermal, Electrical, and Elastic Energy

• Motion, Nuclear, Chemical, and Radiant Energy

Answer explanation

A refrigerator transforms Electrical Energy into Motion, Radiant, Sound, and Thermal Energy. The electrical energy powers the compressor, which creates motion and generates heat, while also producing sound. The light bulb inside creates radiant and thermal energy when the door is opened.
