a)

Gravitational potential energy

b)

Elastic energy

c)

Electrical energy

d)

Chemical energy

2.

Stretching a rubber band gives the rubber band electromagnetic potential energy because the rubber band’s molecules have been forced apart, overcoming the molecules’ electromagnetic attraction.

a)

Electrical energy

b)

Gravitational potential energy

c)

Energy of motion.

d)

Elastic energy.

3.

Applying a voltage to a conductor gives the conductor electromagnetic energy because the electrons have not yet yielded to the electromagnetic force.

a)

Thermal or heat energy

b)

Electrical energy

c)

Gravitational potential energy

d)

Thermal into Chemical.

4.

The electrons in molecules of fuel have electromagnetic potential energy. They are too far away from the nuclei of the product that can be formed during combustion.

a)

Electrical to Thermal.

b)

Resistance

c)

Energy Conversion

d)

Chemical energy.

5.

Changes among solid, liquid, and gaseous states are electromagnetic potential energy because the molecules have overcome the attraction between electrons in one molecule and the nuclei of neighboring molecules.

a)

Thermal into Chemical

b)

Thermal or heat energy

c)

Chemical to Kinetic

d)

Kinetic energy.
