Ascientist discovers a new substance. the molecules of the substance form hydrogen bonds with each other. when the molecules lose a lot of energy, the hydrogen bonds hold them relatively far apart. based on this information, what can the scientist infer about the substance?

Answer is: It expands when it freezes.

When molecule frezes, it lose energy. When molecules are far apart, it means the volume is greater and it expands.

For example, ice expands when water is freezing.

Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.

it takes on an electronical energy
