Problem 3You have just finished preparing a 750 g batch of coffee at a temperature of 95.0 °C. You pourit into a vacuum-sealed stainless steel thermos which is at room temperature (20.0°C). Thethermos's inner layers (side walls of the container plus the steel portion of the lid) have acombined mass of 189 g. Before screwing on the lid, you add 15 g of cream from the refrigerator(4.0 °C). What is the temperature of your beverage after a long time has passed? Assume thatthe thermos is a perfect insulator, and use the following specific heat values: Ccoffee = 4.186J/g°C,Csteel = 0.460/gc, and Ccream = 3.350/g°C.

To solve this problem, we can use the principle of energy conservation, which states that the total…
