. Most people find waterbeds uncomfortable unless the water temperature is maintained at about 85 °F. Unless it is heated, a waterbed that contains 892 L of water cools from 85 °F to 72 °F in 24 hours. Estimate the amount of electrical energy required over 24 hours, in kWh, to keep the bed from cooling. Note that 1 kilowatt-hour (kWh) = 3.6 ×× 106 J, and assume that the density of water is 1.0 g/mL (independent of temperature). What other assumptions did you make? How did they affect your calculated result (i.e., were they likely to yield “positive” or “negative” errors)?
A newspaper article about the danger of global warming from the accumulation of greenhouse gases such as carbon dioxide states that "reducing driving your car by 20.0 miles a week would prevent release of over 1000. pounds of CO₂ per year into the atmosphere." To decide if this is a reasonable statement, calculate the reduction in the number of pounds of CO₂ a car would release in a year if its use was decreased by 20.0 miles per week. Think about the effects of possible variations in gas mileage on your answer. Gasoline is a complex mixture of hydrocarbons. In your calculations, assume that gasoline is octane (molecular formula C8H₁8) and that it is burned completely to CO₂ and H₂O in the engine of your car. Also assume that the car averages 26.4 miles per gallon and that the density of octane is 0.703 g cm-3. Reduction in pounds of CO₂ released = lb
