LIQUIDS

What do you mean by PROPERTIES of LIQUIDS?

• The attraction between water molecules at the surface of water

• The process in which a substance changes from its liquid to gas

• The measure of a fluid’s resistance to flow

• The ability of a substance to dissolve in a given amount of solvent at a specified temperature

What do you mean by VAPORIZATION?

• The attraction between water molecules at the surface of water

• The process in which a substance changes from its liquid to gas

• The ability of a substance to dissolve in a given amount of solvent at a specified temperature

• The measure of a fluid’s resistance to flow

Which will exert a higher vapor pressure? Why?

• Acetone - because it has a lower molar heat of vaporization

• Water - because it has a higher boiling point

• Acetone - because it has a higher molar heat of vaporization

• Water - because it has a lower boiling point
