TRUE OR FALSE
SURFACE TENSION:
I. A decrease is due to the weakening of the hydrogen bonds of water molecules
II. It is increased when a surfactant is added
III. Soap lowers surface tension of water resulting to the shrinkage of molecules on the surface
2. Which statement best describe gases?
a. Gases consist of molecules that have enough spatial separation that the intermolecular
bonding characteristics of liquids and solid is absent.
b. Gases are almost incompressible. In liquids molecules are close to each other.
c. Gases are characterized by structural rigidity and resistance to a force applied to the
surface.
d. Gases are in the state in which matter adapts to the shape of its container but varies only
slightly in volume
