Properties of Water

What is water called because it dissolves more substances than any other substance?

• the universal solvent

• supreme solvent

• the universal solute

• planetary ruler

How does water dissolve so many other polar substances, like NaCl (salt)?

• it breaks apart the chemical bond holding the Na molecule to the Cl molecule then surrounds each

• it creates the chemical bond holding the Na molecule to the Cl molecule then surrounds each

• it surrounds the NaCl molecule and changes the density

Water "beads" up on the surface of this plant due to​ (a)   and "sticks" to the plant due to​ (b)  

• cohesion

• adhesion

• capillary action

• transpiration

When water freezes in the ocean, the ice floats to the surface. What property explains this phenomenon?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

Water is considered a polar molecule because it has -

• a slight positive charge on one end and a slight negative charge on the other.

• adhesion

• cohesion

• it has charges distributed throughout the molecule

Water molecules are attracted to other water molecules. What is this property of water called?

• adhesion

• cohesion

• surface tension

• capillary action
