Electrical energy is energy that travels in moving electric charges called:

• electrons

• protons

• neutrons

• nucelli

Chemical energy is energy stored in chemical bonds. So, chemical energy is:

• kinetic energy

• potential energy

• both

• neither

What type of energy transfer happens when energy is given off by the sun?

• Convection

• Conduction

• Radiation

Answer explanation

This type of energy transfer is radiation. There is no mass between the sun and the Earth that it heats. The electromagnetic waves carry the energy to Earth.

What type of energy transfer happens when you place ice on sprained ankle?

• Convection

• Conduction

• Radiation

Answer explanation

This type of energy transfer is conduction. The ice is place directly on the ankle, which is the heat source. The thermal energy moves from the body to the ice and melts the ice. The ankle feels cold because some thermal energy left to melt the ice.

The transfer of energy through materials: solid, liquid, gas.

• Conduction

• Convection

• Radiation

Answer explanation

In order for conduction to happen, the materials must be in direct contact with the heat source.
