Step by step
Solved in 2 steps
- The energy we require to live comes from the chemically stored potential energy in food, which is transformed into other energy forms during the metabolism process. What happens to a person whose combined work and heat output is less than the energy consumed? What happens when the persons work and heat output is greater than the energy consumed? Can an undernourished person perform extra work without extra food? Defend your answers.What is the ultimate source of energy in coal, oil, and wood? Why do we call energy from wood renewable but energy from coal and oil nonrenewable?In a decentralized energy generation system, analyze how solar thermal energy can contribute to environment and social sustainability? To add value to your answer, you may use any solar thermal energy application or any other practical use that you witnessed somewhere (even a case study).
- What is ‘renewable source of energy’ and why is it important?To combat wasteful habits, we often speak of “conserving energy,” by which we mean turning off lights and hot water when they are not being used and keeping thermostats at a moderate level. In this chapter, we also speak of “energy conservation.” Distinguish between these two usages.Distinguish between high-quality energy and low-quality energy in terms of organized and disorganized energy. Give an example of each.
- demonstrates a direct energy transfer? demonstrates a direct energy transfer? When the traffic signal turns red (1) automobiles stop. When water is boiled, steam is (2) produced. After a field is plowed and fertilized. (3) corn is planted. (4) When the fire alarm rings, firetrucks rush off. (5) If a letter has the correct postage, the letter carrier delivers it.PV cell is indirect method of solar energy (true or false)?Can we correctly say that hydrogen is a new source of energy? Why or why not?
- At a certain location, the solar power per unit area reaching Earth’s surface is 200 W/m2, averaged over a 24-hour day. If the average power requirement in your home is 3 kW and you can convert solar power to electric power with 10% efficiency, how large a collector area will you need to meet all your household energy requirements from solar energy? (Will a collector fit in your yard or on your roof?)(b) Wind energy is a dynamic form of solar energy. Explain, how?.What are the pros and cons of Geothermal energy when youl will use it to power your house?
