As part of a project in the General Physics III course, a group
of students must.
follow the following experiment:
i. Immerse an aluminum sphere in a vessel containing boiling water
such that it has a diameter d = 2.54533 cm when it reaches
equilibrium with the boiling water.
that when it reaches equilibrium with the boiling water it has a
diameter d = 2.54533 cm.
ii. Place a copper ring of mass 21.6 g in a container in which
coexist
water and ice such that when it reaches equilibrium with the water
and ice it has an internal diameter D = 2.54000 cm.
D = 2.54000 cm.
iii. After waiting a few minutes, the sphere and the ring are
removed from the respective containers and the sphere is placed on
top of the ice.

iv. Wait until the sphere and the ring reach equilibrium.
Once the experiment is done, as part of the analysis, the group of
students must answer a few questions.
answer a few questions. Suppose you are part of that group, and you
have to answer the following questions based on the experiment
described above.
following questions from the experiment described above:
A. If, once equilibrium is reached, the sphere passes through the
ring, and considering that there is no energy exchange in the form
of an
that there is no exchange of energy in the form of heat with the
surroundings, what is the equilibrium temperature of the
ring-sphere system?
equilibrium temperature of the ring-sphere system?
B. What is the mass of the sphere?
C. What must be the temperature of the sphere so that the density
is 0.15% higher than when it was immersed in the sphere?
compared to when it was immersed in the container of boiling
water?
D. Explain, qualitatively, why the temperature of a sphere must be
increased to decrease the density of the sphere?
