Question
Two aircraft rivets, one of iron and the other of copper, are placed in contact with each other in a calorimeter that has an initial temperature of 20.0 C. The following data is known: Will heat How from Fc to Cu or from Cu to Fe? Explain your answer in one sentence using correct grammar. What assumption is made in this experiment? What piece of information do you not need because you made this assumption? What is the maximum final temperature of the system? The heat capacity of the container is negligible.Explanation / Answer
a)
heat will flow from copper to iron because copper is at higher temperature
b)
assumption amde is that no heat is lost to the surrounding
c)
Let final temperature be ToC
usE:
heat lost by copper= heat gained by iron
15*0.385*(100-T) = 25*0.449*(T-0)
577.5 - 5.775*T = 11.225*T
T = 34 oC
Answer: 34 oC
