Energy is best described as:

• A sum total of an oibject's electrons

• A property of matter

• An unstable chemical compound

• The temperature of a given object

Potential is to kinetic as saving is to ______.

• Spending

• Investing

• Borrowing

• Sharing

Why does it take so much energy to keep the electrons of an atom close together?

• The nucleus is negatively charged

• Like charges repel each other

• Electrons get bigger as the distance between them increases

• They contain powerful electrolytes

What do batteries create that allows them to provide a power supply?

• A current

• A magnetic field

• Radioactive decay

• Static shock

Which grouping properly labels the core parts of a battery?

• A=anode, B=seperator, C=Cathode, D=collector

• A=seperator, B=anode, C=collector, D=cathode

• A=cathode, B=collector, C=anode, D=seperator

• A=anode, B=collector, C=cathode, D=seperator

How does the function of metals differ in anodes and cathodes?

• Anode metals releases electrons; cathode metals collect electrons

• Anode metals collect electrons; cathode metals release electrons

• Anode metals conduct electricity; cathode metals do not

• Cathode metals conduct electricity; anode metals do not

A battery loses the ability to provide energy when:

• The device it's powering is turned off.

• Its electrolyte starts to dissolve

• It can no longer create chemical reactions

• Electrons are pushed into the anode

What would be the most likely result of a hole in a battery's separator?

• The electric current produced by the battery would run in reverse

• Current would flow from the battery whether it was plugged into a device or not

• The battery would go dead as electrons from the anode moved directly into the cathode

• The battery would continue to operate normally

What happens when you recharge a battery?

• It strengthens the chemical reactions

• It increases the voltage of the battery

• It converts potential energy into kinetic energy

• It reverses the direction of the current
