Energy Transfer
Mirrors in a solar sand plant might store this type of energy.
What is Solar Energy?
20% of 10.8 MJ (megajoules)
2.16 MJ
One benefit of a hydroelectric system is that water is this type of resource.
What is renewable?
[BLANK] cannot be created or destroyed (Hint: an M word that makes up everything like tables and my hand)
What is Matter?
The opposite of demand and the energy that is available is called…
What is supply?
Hot sand transfers thermal energy to water, causing the water to become this (Hint: This also happens in Nuclear Power Plants)
What is steam?
If a system is 20% efficient, this percentage of energy is not delivered to communities
What is 80%?
Name one factor engineers must consider before building nuclear power plants
Cost, environment change, safety, or if Mr. Yaeger says your answer is good enough
Energy can be motion, sound, light, or this form of energy that might make you sweaty
What is heat/thermal energy?
The definition of energy storage
What is energy that is saved for later?
Much of the energy that does not reach communities is sent out into its [BLANK]
What is surroundings?
A turbine receives 10.8 MJ of steam energy. Multiply by 0.2 to find the useful energy.
What is 2.16?
Communities should consider whether there is enough [BLANK] to build BIG power plants
What is space/room/resources/money/or if it is close enough?
This form of generating power and electricity involves the movement of water to move machines
What is hydroelectric power?
This form of water pushes turbines in a nuclear power plant (Hint: this happens when water is made really hot)
What is steam?
Create the correct order:
Steam, Water, Electricity, Turbine, Heated Water
Water, Heated Water, Steam, Turbine, Electricity
If 10,000 m² of panels each provide 2.16 MJ, this amount of energy is available
What is 21,600 MJ?
Engineers evaluate solutions based on cost, safety, and this factor related to how well a system works (a word that starts with E)
What is efficiency?
The charge of an electron is this
What is negative?
Electricity is the movement of these
What are electrons?
Steam causes this device to spin and help generate electricity in a generator.
What is a turbine?
If 21,600 MJ is shared among 2,000 people, this is how much energy is available per person
What is 10.8 MJ?
This part of a system allows energy to be stored for later
What is the battery?
Although matter and energy cannot be created or destroyed it can do this
What is transfer, transform, move, be pushed, Mr. Yaeger will take a lot of answers?
It is important to store energy when using solar power during the day because…
What is there is no sun at night?
