Energy Transformation
Environment & Society
100
This is the law of electric charges.
What is opposite charges attract and like charges repel?
100
This is the energy transformation in a light bulb.
What is electrical --> light/thermal?
100
This is the issue with traditional electricity generation.
What is pollution (CO2, SO2, NOx)?
200
This is why insulators do not conduct electricity.
What is they hold their electrons tightly?
200
This is the unit for power.
What is watts?
200
This is one of the drawbacks of technology advancements.
What is expense, security, waste disposal, etc?
300
This is the difference between amps and volts.
What is amps = current = rate of flow or how much? What is volts = voltage = energy of each charged particle or "push"?
300
This is the device that measures resistance.
What is an ohmmeter?
300
This is using resources at a rate that can be maintained indefinitely.
What is sustainability?
400
This is why a rechargeable battery is rechargeable.
What is the chemical reactions can be reversed?
400
This is the steps for converting energy in Joules to kilowatt hours.
What is divide by 1000, divide by 3600?
400
This is the code used by computers to compute all information.
What is binary?
500
This is the parts and functions of an electrolytic cell.
What is cathode = positive (copper), anode = negative (zinc), and electrolyte solution (acid)?
500
This is the difference between a step-up transformer and a step-down transformer.
What is step-up = increased voltage & more coils on secondary, step-down = decreased voltage & less coils on secondary?
500
This is the alternative energy source that converts gravitational energy into mechanical energy, then into electrical energy.
What is a hydroelectric dam?
