- List four different forms or types of energy. Give one example of a conversion from each of these forms to another form.Explain, in terms of the definition of power, why energy consumption is sometimes listed in kilowatt-hours rather than joules. What is the relationship between these two energy units?An electric water heater consumes 5.00 kW for 2.00 h per day. What is the cost of running it for one year if electricity costs 12.0 cents/kW h ? See Figure 20.41. Figure 20.41 On-demand electric hot water heater. Heat is supplied to water only when needed, (credit: aviddavid, Flickr)

- One 9-volt battery contains 19.0 thousand joules of energy. A 4-pack of 9-volt batteries cost $14.40 at Lowe's. Estimate the cost of battery energy in dollars per kilowatt-hour. Energy conversions are available in Section 2.2 of the textbook. Round your final answer to the nearest $10 per kilowatt-hour.*8) Describe two ways to conserve electrical energy by making small changes to your daily habits.1) Determine the change in chemical energy each second required to produce this increase in electric potential energy. 2) If there are roughly 7×10^11 of these cells in the body, how much chemical energy is used in pumping sodium ions each second? 3) Estimate the fraction of a person's metabolic rate used to pump these ions. Assume the metabolic rate to be 100 W.
- Assuming that the diet of an average Canadian consumes 2,500 food calories per day (1 cal=4200 J), compare the amount of energy consumed by a Canadian family of 5 in one year in their diet with the amount of electrical energy their household consumes. The average annual electricity usage of a family of 5 in n area can be estimated by 6000+5x1,600 kWh. What is the ratio of electrical energy consumption to caloric energy consumption for this family of 5? (1kWh=3,600,000 J). Your Answer: AnswerUse a diagram to explain how electrical energy is generated and transmitted from power plants down to our houses.Choose a source of energy from any of the renewable and non- renewable resources and explain how it is converted to electrical energy. Write a brief explanation on how it works.
