The gallium atoms will be moving faster on average.
The gallium atoms will gain potential energy, moving freely from each other.
The gallium atoms will gain potential energy, moving freely from each other.
The gallium atoms will gain kinetic energy.
The gallium atoms will gain kinetic energy.
The gallium atoms will increase in temperature.
All of the above responses are correct.
Are you sure?
I apologize for the repetition in my response. Only the first three responses are correct. When the gallium melts in the person's hand, the gallium atoms will be moving faster on average, gain potential energy as they move freely from each other, and gain kinetic energy. However, the increase in temperature is not necessarily a guaranteed outcome. Temperature is a macroscopic measurement that depends on the average kinetic energy of all the particles in a substance. While the individual gallium atoms are gaining kinetic energy, it may not necessarily result in a significant increase in temperature.
The correct answer is:
The gallium atoms will be moving faster on average.
The gallium atoms will gain potential energy, moving freely from each other.
The gallium atoms will gain kinetic energy.
The gallium atoms will increase in temperature.
When gallium is heated and reaches its melting point, the energy input causes the atoms to move faster on average. This increase in speed results in an increase in kinetic energy. As the gallium atoms gain kinetic energy, they also gain potential energy, allowing them to move more freely from each other. This increase in energy and motion leads to a rise in temperature, resulting in the melting of the gallium.
