Solve the following
7) You add 25 g of milk at 10o C to 200 g of coffee (essentially water) at 70o C. The coffee is in a Styrofoam cup. If the specific heat of milk is 3800 J/kg*oC, by how much will the coffee temperature decrease when the milk is added? Indicate any assumptions you made. The specific heat of water is 4180 J/kg*oC,
8) The kayak of a 70-kg man tips and he falls into a cold stream. When he is rescued from the cold water, his body temperature is 33 °C (91.4 °F). He is placed in 50 kg of warm bath water at temperature 41 °C (105.8 °F). What is the final temperature of the man and the water?
