Question:

A 20.0-g block of iron at 50.0oC and a 20.0 g block of aluminum at 45oC are placed in contact with each other. Assume that heat is only transferred between the two blocks.
A 20.0-g block of iron at 50.0oC and a 20.0

a. Draw an arrow indicating the heat flow between the blocks.
b. What is the sign of qsys for the aluminum when the blocks first come into contact?
c. What will you observe when qsys for the iron is zero?
d. Estimate the temperature of the Al and Fe blocks when qsys of the iron equals qsys of the aluminum.
