Checkpoint 12
Listenâ–¸
Which choice most accurately explains what happens to the attractive forces between molecules when water changes to steam, and what becomes of the energy added
during this phase change?
When water changes to steam, bonds between molecules are created. After reaching the boiling point, energy is used to alter the strength of existing attractive
forces and change the kinetic energy of the molecules
When water changes to steam, bonds between molecules are created. After reaching the boiling point, energy is used to overcome attractive forces, but does
not affect the kinetic energy of the atoms.
