B7: Properties of Water Review

What is adhesion?

• Water sticking to other water molecules

• Water sticking to other materials

• Water climbing up

• Unequal sharing of electrons which cause a positive hydrogen change and negative oxygen charge

What is cohesion?

• Water sticking to other water molecules

• Water sticking to other materials

• Water climbing up

• Unequal sharing of electrons which causes a positive hydrogen charge and negative oxygen charge

What is surface tension?

• Water sticking to other water molecules

• Water sticking to other materials

• Water climbing up

• Measure of how difficult it is to break the surface of a liquid.

What is polarity?

• Water sticking to other water molecules

• Water sticking to other materials

• Water climbing upwards

• Unequal sharing of electrons, which causes positive hydrogen atom and negative oxygen atom

How does a surfactant work?

• It decreases surface tension by weakening hydrogen bonds

• It increases surface tension by weakening hydrogen bonds

• It increases the density of the substance

• It is water's ability to climb upwards

What is universal solvent?

• Water's ability to dissolve many substances because of its polarity

• Water climbing up

• Water molecules sticking to water molecules

• Water molecules sticking to other substances

What is the pH of water?

• It is 7; neutral

• It is 7; acidic

• It is 7; basic

• It is 9

What is capillary action?

• Water climbing up, like the roots of plants.

• Water attracted to other water molecules.

• Water attracted to other materials.

• Unequal sharing of electrons, which causes a positive charge on hydrogen and negative charge on oxygen
