Bot you are so wrong!
Here are all of the answers for the Quick Check.
What is kinetic energy? Answer: The energy of motion.

The gallium in the image is melting in the person’s hand. Which changes will occur on a microscopic level? Answer: The gallium atoms will gain potential energy, moving freely from each other.
Which object will have particles with the highest average kinetic energy? Answer: a drop of water at 90°C
As water becomes warmer, boils and then becomes water vapor (steam), what happens to its kinetic and potential energies? Answer: The particles gain both potential and kinetic energy.
