2.Which choice most accurately explains what happens to the bonds between atoms 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 change bond strength and change the kinetic energy of the atoms.
When water changes to steam bonds between molecules break apart. After reaching the boiling point, energy is used to break bonds, but does not affect the kinetic energy of the atoms.

When water changes to steam bonds between molecules break apart. After reaching the boiling point, energy is used to change bond strength and change the kinetic energy of the atoms.

When heat is applied to water, the bond between the molecules start to loosen up and molecules starts separating hence it from changes from liquid to gas or steam.

At this time molecules have greater kinetic energy which is given to them in form of heat. Hence apart from all options given, D is the correct one which states that :

"When water changes to steam bonds between molecules break apart. After reaching the boiling point, energy is used to change bond strength and change the kinetic energy of the atoms."

Answer:

When water turns to steam,

D) the water absorbs energy which causes the water molecules to have more kinetic and potential energy changing their configuration from a liquid to a gas.
