Question

3. jack is using plastic beads to model water molecules in each state of water. how shoule she the beads to represent water molecules in a solid? a they should be far apart and glued in place b. they should be close together and glued in place c. they should be far apart and allowed to move reely d thay should be close together

Answer 1

Jack should arrange the beads close together and slide past each other to represent water molecules in a liquid.

How are the molecules of water arranged when water is in its liquid phase?

• Each water molecule contains two atoms of hydrogen and one atom of oxygen, arranged such that one side of the molecule (nearest the hydrogens) is positively charged while the other side (nearest the oxygen) is negatively charged.
• They’re arranged randomly, and in random motion.
• In fact, they’re not even keeping the same hydrogen atoms, as they are constantly popping off and reforming on the nanosecond time scale.
