I’m working on a physics writing question and need a sample draft to help me understand better.
- Energy conservation means something different for most people than the actual scientific definition. How do you suppose that this happened?
- One of the important concepts in the science of thermodynamics is the idea of efficiency. It tells us the percentage of useful energy obtained when a fuel is burned to perform useful work. Why is this important when discussing the sourcing of energy?
- Explain why you can’t just open the refrigerator door to cool off the kitchen on a hot day. Why does an air conditioner work where the refrigerator will not?
- Different sources of energy have different levels of efficiency. When considering this we need to consider the whole stream of energy production from mine to finished product. For each of the sources of electrical energy listed below, discuss the features which reduce the efficiency of that source. Some of these may be waste products but sources of inefficiency may also include other issues which are particular to that source. Note that the answers to this question should be in complete sentences and not simply a list. Each of the four answers to this question should be at least 100 words.
- Coal
- Nuclear
- Solar
- Wind
