Question

There is a piece of gallium in the middle of a persons hand melting.
The gallium in the image is melting in the person's hand. Which changes will occur on a microscopic level?
A. The gallium atoms will gain kinetic energy.
B. The gallium atoms will be moving faster on average.
C. The gallium atoms will increase in temperature.
D. The gallium atoms will gain potential energy, moving freely from each other.

Answer 1

Based on the description of gallium melting in the person's hand, the correct changes that occur on a microscopic level would be:

A. The gallium atoms will gain kinetic energy. B. The gallium atoms will be moving faster on average. C. The gallium atoms will increase in temperature.

All three of these options are related to the process of melting, where the increase in temperature leads to greater kinetic energy and faster movement of the atoms.

Option D is somewhat misleading; while the gallium atoms do move more freely in the liquid state, the term "gain potential energy" isn't typically used in this context. Instead, they gain kinetic energy and become less arranged than they are in the solid state.

Therefore, options A, B, and C are correct regarding the changes that occur on a microscopic level as gallium melts in the hand.

Answer 2

choose one that is closest to the correct answer

Answer 3

The closest answer to the correct change that occurs on a microscopic level when gallium melts in a person's hand is:

A. The gallium atoms will gain kinetic energy.

This option captures the essence of what happens during the melting process, as the increase in temperature leads to increased kinetic energy of the atoms.
