20. What is your opinion why ice cubes float on water considering solids have
greater density than liquids?
A. The molecules of solid water attract each other compared to liquid
molecules.
B. The water molecules in ice are more closely packed together than in liquid
water.
C. The water molecules in ice cubes are less closely packed together than in
liquid water.
D. There are no spaces between molecules in ice resulting to more particles
per volume in liquid water than solid water.
21. What is your opinion why soap bubbles are spherical?
A. Water spreads out when hydrogen bonds are disturbed making surface
tension.
B. Soaps and detergents molecules attract each other make greater surface
tension.
C. Drops of water are spheres in shape, surface area of spheres are smaller
than any other shape of same volume.
D. Soaps and detergents increase the surface tension of water by disrupting
the hydrogen bonds between molecules.

25. You measure exactly 100 millilitres of water in a graduated cylinder. You heat
the water to 100 °C and notice that the volume increases to 104 millilitres. Using
what you know about the attractions between water molecules and the way heating
affects molecular motion, what would happen to the volume of water in the cylinder
when it is heated?
A.
As molecular motion decreases, the space between molecules also
decreases.
B. Liquid molecules decrease when heating resulting to increase in volume.
C. The molecules in hot water move closer together, accounting for the
increased volume.
D. The molecules in hot water move slightly further apart, accounting for
the increased volume.
