IMFS and States of Matter

Water has a higher capillary action than mercury due to

• higher dipdip forces between the water molecules

• strong cohesive forces within water

• very significant induced inter-molecular attractions

• weak adhesive forces in water

• strong cohesive forces in water which work with strong adhesive forces between water and the capillary material

Small drops of water tend to bead up because of

• high capillary action

• the shape of the meniscus

• the resistance to increased surface area (i.e., molecules prefer to attract each other rather than the surface)

• low London dispersion forces

• weak covalent bonds

As you go down the noble gas family on the periodic table, the boiling temperature increases. This trend is due mainly to

• an increase in hydrogen "bonding"

• a decrease in dipdip forces

• the lower atomic masses as you go down the family

• an increase in LDF

Several liquids are compared by adding them to a series of 50 mL graduated cylinders, then dropping a steel ball of uniform size and mass into each. The time required for the ball to reach the bottom of the cylinder is noted. This method is used to compare the differences in a property of liquids known as ________

• surface tension

• buoyancy

• capillary action

• viscosity

• surface contraction
