Types of Energy Sources

If you hook up a buzzer to a battery pack, what is the source of energy for the buzzer?

• chemical potential energy
• electrical energy
• mechanical energy
• sound energy

If you hook up the photovoltaic cell to the windmill with bright light shining on the PVC, what is the source of energy that the PVC is converting to electricity?

• light alone
• chemical alone
• light/chemical
• mechanical

If you hook up any of the components of the energy conversion kit, in what form is the energy transmitted from source to consumer?

• mechanical
• kinetic
• electrical
• nuclear

What is the windmill powered by if it is hooked up to the photovoltaic cell (PVC)?

• light
• chemical
• light and chemical
• electrical

What does the consumer convert electrical energy to in the hand generator and motor combo?

• mechanical energy
• potential energy
• electrical energy
• nuclear energy

What are clouds made of?

• water vapor & ice crystals
• ice crystals & liquid
• gas & water

When condensation or deposition occurs in the change of phase of a cloud to liquid or solid, what is transferred to the surroundings?

• air
• temperature
• thermal energy
• ice

When evaporation or sublimation occurs in oceans, what is transferred to or from the surroundings.

• gas
• thermal energy is transferred from the surroundings (cooling of surroundings)
• thermal energy is transferred to the surroundings (warming of surroundings)
• Nothing -- it is in dynamic equilibrium

What is super-cooled water?

• Liquid water that is "slushy."
• Ice that is colder than 0 ^oC
• Liquid water that is colder than 0 ^oC
• Liquid that is warmer than 4 ^oC

Weather is what you wear and climate is what is in your closet.  Hmmm?  What does that mean?

• Your closet reflects the range of weather you will experience in your area over a long period of time
• Whether or not, here weather changes!
• Bell whethers tell us that something wicked, this way comes.
• Weather is constant over a long period of time while climate depends on where you will travel
