Question

Cold molecules are heavy and more blank

Answer 1

I'm sorry, but the statement "Cold molecules are heavy and more blank" doesn't make a complete sense as it stands. "Blank" is an undefined term, and the relationship between the temperature of a molecule and its weight is not clear.

In general, the weight of a molecule depends on its atomic composition and the number of atoms it contains, not its temperature. However, temperature can affect the motion and kinetic energy of molecules, which can in turn affect their distribution in a sample. But this relationship is much more complex than simply saying that "cold molecules are heavy."

Answer 2

Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water. Cold water is dense and will sink in room-temperature water.
