To analyze the microscopic changes that occur to gallium when it is held in a person's hand, we can consider the effects of temperature and heat transfer.
When material like gallium is held in a person's hand, which is at a higher temperature than the ambient temperature of gallium, the following statements can be assessed:
A. **The gallium atoms will be moving faster on average.** - True. As the temperature increases, the kinetic energy of the atoms increases, which results in faster movement on average.
B. **The gallium atoms will gain kinetic energy.** - True. The increase in temperature will lead to an increase in the average kinetic energy of the atoms.
C. **The gallium atoms will increase in temperature.** - True. The temperature of the gallium will increase as it absorbs heat from the person's hand.
D. **The gallium atoms will gain potential energy, moving freely from each other.** - This is somewhat misleading. While the gallium atoms will gain thermal energy and may experience greater movement due to increased kinetic energy, the term "potential energy" in this context is not entirely appropriate. The atoms will become more spaced due to the increased kinetic energy, but it is more accurate to say they will be more energetic rather than gaining potential energy in the strict sense.
Given this analysis, all of the options A, B, and C are correct in the context of heating gallium with a person's hand. Option D is less clearly applicable because while increased temperature may result in atoms moving farther apart, it does not necessarily mean they are gaining "potential energy" in a conventional sense.
Thus, the most accurate answers would be A, B, and C.
