Question

1. thermal energy is added to water. which of the following describes the new state of matter? an exothermic process has caused the phase change. particles are attracted to each other and form bonds. bonds have been broken that hold particles in place. kinetic energy of particles has decreased.

Explanation:

When thermal energy is added to water, bonds (like intermolecular bonds in ice melting or liquid water vaporizing) that hold particles in place break. An endothermic process (not exothermic) absorbs heat for phase change. Particles moving more (kinetic energy increases, not decreases) and breaking bonds, not forming, happens. So the correct description is bonds holding particles in place are broken.

Answer:

Bonds have been broken that hold particles in place.
