Explain what is the final temperature of spoon coffee

Reference no: EM13213170

A stainless steel spoon weighs 27.7 g and is at a temperature of 18.5 oC. It is immersed in 82.7 mL of hot coffee (T = 84.0 oC) in a Thermos flask. What is the final temperature of spoon + coffee? (Assume that the heat capacity of the spoon is the same as that of pure iron and that the heat capacity of the coffee is the same as that of pure water.)
