Question

part e
water can exist in three different states of matter: solid, liquid, and gas. the water molecules are the same in each state, but the distance between them changes as water changes state. space your four molecules evenly on one sheet of paper. now place the second sheet of paper next to the first sheet, so the long edges of the sheets are touching. space your four molecules evenly over both sheets of paper. compare the two models. does this demonstration show how the distance between water molecules can change? were the molecules more tightly - packed on one or two sheets of paper? explain.

Explanation:

The demonstration uses paper - space as a model for molecular spacing. When four molecules are spaced on one sheet, they are more tightly - packed compared to when they are spaced over two sheets. This is similar to how water molecules are more closely packed in the solid and liquid states (less space between them) compared to the gas state (more space between them).

Answer:

Yes, this demonstration shows how the distance between water molecules can change. The molecules were more tightly - packed on one sheet of paper because the same number of molecules were distributed over a smaller area.
