Eric performs an experiment in class with a brass ball and ring. He starts with both the ball and ring at room temperature (22oC). When both the ball and ring are at room temperature, the ball easily slides through the brass ring. Eric then places the brass ball only over a flame and keeps it over the flame for 2 minutes. As soon as he removes the ball from the ring he tries to place it through the brass ring, but this time the ball does not slide through the ring.

Which of the following statements explains why the ball no longer fits through the ring? Select two correct answers.

A As thermal energy was transferred to the brass ball, it underwent a phase change. As thermal energy was transferred to the brass ball, it underwent a phase change.

B As thermal energy was transferred to the brass ball, the particles gained kinetic energy. As thermal energy was transferred to the brass ball, the particles gained kinetic energy.

C As thermal energy was transferred to the brass ball, the particles start to vibrate. As thermal energy was transferred to the brass ball, the particles start to vibrate.

D As thermal energy was transferred to the brass ball, it expanded. As thermal energy was transferred to the brass ball, it expanded.

E As thermal energy was removed from the brass ring, it contracted. As thermal energy was removed from the brass ring, it contracted.

F As thermal energy was removed from the brass ring, the particles lost kinetic energy. As thermal energy was removed from the brass ring, the particles lost kinetic energy.
