Part A -  Objectives/ Guide Questions  

1. Name the four states of matter and describe physical and chemical changes of matter.

 

2. State, and explain the “Laws of thermodynamics”, that describe what happens to energy as it is changed from one form to another.

 

3. Define what is meant by energy efficiency and how is it measured?

a) Indicate several methods to improve energy efficiency.

b) Explain “end use”, and “total use” energy, and how they apply to our energy use. 

 

4. For the following conventional energy sources describe how they are obtained, advantages and disadvantages, percent currently used, and date of depletion.

 

            The following links lead to charts that will help you identify depletion dates:   How Long - 1  and     How Long - 2
