What property of water allows it to dissolve many substances?

• Cohesion

• Adhesion

• Polarity

• Surface tension

Which of the following is a result of water's high surface tension?

• Water droplets forming spherical shapes

• Water flowing uphill in a thin tube

• Ice floating on water

• Water dissolving salt

What causes hydrogen bonds to form between water molecules?

• The high kinetic energy of water molecules

• The ionic bonds between hydrogen and oxygen atoms within a water molecule

• The partial positive charge of hydrogen atoms and the partial negative charge of oxygen atoms

• The covalent bonds that hold hydrogen and oxygen atoms together

Cohesion in water refers to:

• The attraction between water molecules and other substances

• The attraction between water molecules

• The ability of water molecules to form hydrogen bonds with non-water molecules

• The resistance of water to increase its surface area

Which property of water is responsible for the capillary action observed in plants?

• Density

• Cohesion

• Adhesion

• Both B and C

Surface tension in water is caused by:

• The cohesive forces between water molecules

• The adhesive forces between water and air molecules

• The gravitational pull on water molecules

• The thermal energy of water molecules

The ability of water molecules to stick to other types of molecules is known as:

• Cohesion

• Adhesion

• Polarity

• Surface tension

Why does ice float on water?

• Because ice has a lower density than liquid water

• Because of the cohesive forces between water molecules

• Due to the high surface tension of water

• Because ice has a higher density but is pushed upwards by water currents
