6. Lily is bathing her dog Aubrey. First, he puts 9.75 kg of very hot water into a steel washtub with a mass of 5.92 kg, and the temperature of the water and the tub stabilizes at 62.5 °C. She realizes that this is far too hot, and so she adds some 15.2 °C cold water to the tub to bring the temperature down. The specific heat of steel is 450 J/kg °C, and that of water is 4184 J/kg °C. a. (5 pts) She starts off by adding 2.46 kg of the cold water. What is the final temperature of the water and the tub? b. (5 pts) How much 15.2 °C water must she now add to bring the temperature down to a more comfortable 35.2 °C? c. (4 pts) Describe what “temperature” means in the context of heat transfer.
