The water then acts like a lubrication between the individual molecules.

At low temperatures the individual molecules are locked against rotation.

Another question relates to the structure of the entire tunnel, rather than individual molecules.

The aide kept working the controls until individual molecules rose before the audience.

At the surface, however, the individual molecules do not have as many options.

Indeed, since the 90s, many techniques for probing individual molecules were developed.

This is because individual molecules of the liquid leave and become gas.

So the individual molecules are trapped in an inert has.

While its individual molecules are heavy, the Spectra material itself is not.

Because water is a liquid, individual molecules are free to rotate.
