Campbell Themes in Bio, 🌊 Properties and Chemistry

What are the four emergent properties of water that are

important for life?

• cohesion, adhesion, temp regulation, evaporative cooling and expansion at freezing

• heat of vaporization, high specific heat, high surface tension,

  capillarity

• polarity, hydrogen bonding, high specific heat, high surface

  tension

Water shows high cohesion and surface tension and can

absorb large amounts of heat because of large numbers of

which type of bonds between water molecules?

• Covalent bonds

• Ionic bonds

• nonpolar covalent bonds

• hydrogen bonds

Water shows high cohesion and surface tension and can

absorb large amounts of heat because of large numbers of

which type of bonds between water molecules?

• strong ionic bonds

• nonpolar covalent bonds

• hydrogen bonds

• weak ionic interactions

Water has an unusually high specific heat. What does this

mean?

• At its boiling point, water changes from liquid to vapor.

• A large amount of heat is required to raise the

  temperature of water.

• Ice floats in liquid water

• Salt water freezes at a lower temperature than pure water.

In a glass of old-fashioned lemonade, what is the solvent?

• lemon juice

• sugar

• water

What are the four elements Biology is made of?

• Carbon, Hydrogen, Oxygen, Nitrogen

• Carbon, Helium, Oxygen, Nitrogen

• Carbon, Hydrogen, Silicon, Water

• idk

What is polarity?

• The unequal sharing of electrons in an ionic bond

• The unequal sharing of electrons in a double bond

• The unequal sharing of electrons in a hydrogen bond

• The unequal sharing of electrons in an covalent bond

If you were a spider gliding across a pond in the summer in

Virginia, for what property of water would you be most

grateful?

• adhesion

• cohesion

• high specific heat

• high heat of fusion

Which of the following explains how a pool of water can

crack a boulder sitting in it during freezing weather?
