Properties of Water

Question 1

Water’s Ability:

Answer 1

1. Water exhibits cohersive behavior
2. Water has the ability to moderate temperature
3. Water expands when it freezes (density)
4. Water is a versatile solvent

Question 2

Go into depth: Cohersive Behavior

Answer 2

• Polarity: There is an uneven distribution of electrons between the oxygen & hydrogen atoms
• Hydrogen bonds: A water molecule attracts water molecules which connect via a hydrogen bond

Question 3

Water Temperature

Answer 3

During the day, water traps in heat and at night, water cools

Question 4

Go into depth: Versatile Solvent

Answer 4

• Solution: All the components are evenly distributed throughout
• Solvent: The liquid that does the dissolving
• Solute: Substance that is dissolved

Question 5

Expansion when freezing:

Answer 5

H2O becomes less dense as it freezes
