4. Emily is testing her baby's bath water and finds that it is too cold, so she adds some hot water from a kettle on the stove. If Emily adds 2.0 kg of water at 80 . C to 20.0 kg of bath water at 27 C, what is the final temperature of the bath water? (water - Cp = 4187 J/kg.C) 5. Dominique is fishing and one of his lead weights is left lying in the sun. He picks it up and realizing how hot it is, puts it in the tray of his cooler for a few minutes. Calculate how much heat is lost from the 0.86 kg lead weight as it cools from 78 C to 30 C. (lead - cp = 128 J/kgoC) 5 . 6. Liz is baking a pie and has a piece of aluminum foil lying on the rack under the pie to keep drippings from burning on the bottom of the stove. When she pulls the aluminum out of the oven its temperature is 95 C. she puts it in the sink where it immediately cools to 75. C. If the total amount of heat energy lost form the foil is 75516. J, what is the mass of the foil? (aluminum - Cp = 899 J/kgoc) 6
