Most people find waterbeds uncomfortable unless the water temperature is maintained at about 85 degree f . unless it is heated, a waterbed that contains 892 l of water cools from 85 to 72 degrre 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 x 106 j, and assume tthat the density of water is 1.0g/ml (independent of temperature0. what other assumptions did you make ? how did they affect your calculated result(i. e., were the like to yield "positve" or "negative" errors)?
