What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into thermal energy.

Front

Identify the energy transformation in a television.

Back

Electric energy transforms into radiant (light), sound, and thermal energy.

Front

What energy transformation occurs in a toaster?

Back

Electrical energy transforms into thermal energy.

Front

Describe the energy transformations in a flashlight powered by batteries.

Back

Chemical energy in the batteries transforms into electrical energy, which then transforms into light and thermal energy.

Identify the energy transformations in a campfire.

Back

Chemical energy from the wood transforms into thermal and radiant energy.

Front

What is the first law of thermodynamics?

Back

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.
