​Energy Transfers and Transformations

By Kody Kitchen

Multiple Choice

Which of the following energy transformations occur when a lamp that is plugged into a wall socket is functioning correctly?

• Chemical to light
• Electrical to chemical
• Electrical to light
• Chemical to electrical

Multiple Select

Which of the following is an example of elastic potential energy? (Select two)

• A bow being pulled back to shoot an arrow

• A battery powering up a remote control

• A bike pedaling to power up a light bulb

• A rubber band being stretched to its limit

Explanation

It is Electrical to Light Because...

The electrical kinetic energy has to flow through the lamp before the light energy can occur.

Multiple Choice

What energy transformations take place when a battery-operated radio is in use?

• Electrical to chemical to light
• Sound to chemical to mechanical
• Chemical Potential to electrical to sound

• Light to electrical to thermal

Explanation

It is Chemical Potential to Electric to Sound because...

The battery has chemical energy (Battery acid) which transforms to Electric and then Sound to operate the radio.

Multiple Choice

Which of the following devices transforms electrical energy into mechanical energy?

• An e-reader
• a fan
• a manual pencil sharpener
• ipod

Multiple Choice

The picture shows a microwave oven. As a microwave oven is operated, electrical energy is transformed into all of the following types of energy EXCEPT —

• solar
• light
• thermal
• mechanical

Multiple Choice

Which energy transformation is taking place when you put gasoline in a car?

• thermal -> electrical
• mechanical -> electrical
• chemical -> mechanical
• mechanical -> electromagnetic

Multiple Choice

Solar Energy is transformed to _____ Energy.

• Mechanical
• Solar
• Sound
• Electrical

Multiple Choice

When the light changes, Potential Energy is transformed to _____ Energy.

• Potential
• Mechanical
• Thermal
• Kinetic

Multiple Choice

Electrical Energy is transformed to _____ Energy

• Thermal
• Solar
• Electrical
• None

Multiple Choice

Electrical Energy is transformed to _____ Energy.

• Mechanical
• Solar
• Electrical
• Thermal

Multiple Choice

Mechanical Energy is transformed to _____ Energy.

• Solar
• Mechanical
• Electrical
• Potential

Explanation

It is Electrical Energy Because

The mechanical energy from the wind Transforms the energy into electricity by the wind turbines spinning.

Multiple Choice

The Electrical Energy of the stove is transformed to _____ Energy.

• Solar
• Thermal
• Potential
• Electrical

Multiple Choice

Which of the following is the correct chain of energy transformations that takes place when a flashlight is turned on?

• chemical => electrical => light

• mechanical => electrical => light

• nuclear => chemical => light

• thermal => chemical => mechanical

Multiple Choice

What type of energy is food energy and when eaten is transferred to store in your muscles?

• mechanical

• nuclear

• thermal

• chemical

Explanation

It is Chemical Energy because...

The food we eat has chemical energy for us to survive, so once we eat the food it transfers to our bodies as Chemical energy for us. (No transformation occurs)

Multiple Choice

What is the correct energy Transformation/Transfer chain from the sun to grass to cow?

• light and thermal => chemical => chemical

• light => heat => mechanical => chemical

• light => thermal => mechanical

• nuclear => chemical => potential

Explanation

It is Light to Chemical to Chemical Energy because

The Radiant light energy from the Sun is transformed into Chemical energy for the Plants and then for whatever animal eats the grass the Chemical energy will transfer to that animal.

Multiple Choice

Which of these is an example of light energy being transformed into chemical energy?

• A glow stick lights up when broken.
• Water heated by the sun evaporates.
• A plant makes sugar in the sunlight. (Photosynthesis)

• A battery causes a buzzer to vibrate.

Multiple Choice

Which type of energy transformation occurs when a flashlight shines?

• chemical → thermal → electrical
• chemical → electrical → light
• thermal → chemical → light
• chemical → electrical → chemical
