Energy transfer — Science definition
Defined in 2 courses:
- Energy moving from one object or place to another without necessarily changing form. (Physical Science: Matter, Forces & Energy)
- Movement or transformation of energy, including increasingly dispersed heat. (Life Science: Biology)
Where it is taught
- Energy Transfer & Transformation — Energy & Heat Transfer, Physical Science: Matter, Forces & Energy, Grade 8
- Comparing Photosynthesis & Respiration — Matter & Energy in Living Systems, Life Science: Biology, Grade 10
In use
An energy transfer is when energy moves from one object or place to another without necessarily changing form, like heat flowing from a hot pan into its cooler handle.

Questions using energy transfer
Problem 1
A solar panel charges a battery. Describe the main sequence of energy transfer and storage.
Hints
State what the supplied observations or conditions establish, and separate that from any assumption.
Answer and explanation
Radiant energy arrives from sunlight, electrical energy is transferred, and chemical energy is stored in the battery, with other outputs such as heating.
Problem 2
Energy transfer means energy
- is destroyed
- moves from one place or object to another
- is created
- disappears
Answer and explanation
moves from one place or object to another
Transfer moves energy; transformation changes its form. Neither creates or destroys it.
