When you boil water in a pot, some of the water escapes as steam. Which of the following choices explains what is happening with the water molecules in this scenario?

• The molecules slow down as the kinetic energy increases and move farther apart from one another.

• The molecules slow down as the kinetic energy decreases and move closer together.

• The molecules speed up as the kinetic energy increases and the molecules move farther apart from one another.

• The molecules speed up as the kinetic energy decreases and the molecules move closer together.
