When a solid is in the process of changing into a liquid and extra energy is added to the system, the temperature does not change.
what happens to this extra energy?
a. the bonds between molecules are unaffected because the average kinetic energy does not change. therefore, the molecular motion must increase.
b. the molecular motion of the water must increase while energy in the bonds decreases in order to keep the average kinetic energy the same.
c. the molecular motion does not change because the average kinetic energy does not change. the bonds are unaffected, because bonds do not change when going from solids to liquids. the energy must be needed somewhere else.
d. the temperature does not change during a phase change because the average kinetic energy does not change. therefore, the potential energy in the bonds between molecules must change.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
