When you mix salad oil and water they immediately separate because:
a)
Water does not dissolve oil
b)
Hydrogen bonds form between water molecules
c)
Salad oil is too dense
d)
It depends on what kind of oil you are using
13.
Why does ice float?
a)
As water freezes, it expands and its density decreases.
b)
As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
c)
As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
d)
As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.
14.
If you put a fine mesh screen under a bottle of water the water will not pour out. Why?
a)
The mesh is too small for water to flow through
b)
The square shapes of the mesh do not fit water drops.
c)
The surface tension of the water holds the water molecules together.
d)
It's magic. Sorcery!
