Look up what the two laws of thermodynamics are. Then, after you read what they are, refer back to the coal-burning power plant diagram from yesterday and explain how the two laws of thermodynamics are shown in the diagram.
Examine the diagram of the coal-burning power plant below. From the diagram, identify:
a) One energy transformation b) One energy transfer Hey kids - remember this from first semester?!? Explain how the diagram above (which shows how energy flows through ecosystems) is a series of energy transformations and transfers.
a) What is a difference between biomass energy and coal?
b) What is a difference between hydropower and geothermal energy? a) What is an energy transformation?
b) In the United States, coal is primarily used to generate electricity. State what specific form of energy coal is, and how we transform it to a different type of energy. Watch the video that Mrs. E will show. In the answer to this journal, discuss:
a) Any statement made that you agree with and why b) Any statement made that you disagree with and why c) How you can be a better steward of the Earth on a daily basis. a) Explain why chemical energy is considered a form of potential energy.
b) Explain why thermal energy is considered a form of kinetic energy. How is air pollution connected to how we get our energy?
The purpose of the question today is to see what you know about our next unit. Your answers will help me prepare what we are going to do during the unit.
List everything you know about: a) Nonrenewable energy sources b) Renewable energy sources c) Ways in which we harm the environment through our use of these energy sources |
