What happens to water molecules when a large quantity of thermal energy is added to water in the liquid state?

• The more thermal energy added, the greater the attraction between molecules.

• The molecules gain kinetic energy, more farther apart, and become a gas.

• The water molecules become packed closer together, and their temperature increases.

• Each molecule gives up kinetic energy and eventually stops moving.
