Question

categorization 5 points
categorize each of the following properties of water and their examples.
(note: you will use all the definitions and examples).
expansion upon freezing
:: water expands when it freezes
:: ice floats on top of the water
:: aquatic organisms can survive in lakes and ponds even in the winter when ice forms.
cohesion and adhesion
:: when water molecules stick to other water molecules
:: allows water to travel up plants
hydrogen bonds
:: bond between the hydrogen atom of one water molecule and the oxygen atom of another molecule
possible answers
:: this property allows water to be a universal solvent, expand when it freezes, absorb a lot of heat, and giving it cohesion and adhesion
:: when water molecules stick to other polar molecules
universal solvent
:: dissolves salts and sugars
:: helps with biochemical reactions in aquatic environments because many substances can dissolve in it
:: can dissolve more substances than another liquid
high specific heat capacity
:: water can absorb quite a bit of energy before changing from a liquid to a gas
:: bodies of water do not change temperature as quickly as the air
:: organisms are mostly water and can regulate their body temperatures because of this property
:: water takes a long time to boil

Explanation:

To categorize the properties of water and their examples:

1. Expansion upon freezing

• Definitions/Examples:
• water expands when it freezes
• ice floats on top of the water
• aquatic organisms can survive in lakes and ponds even in the winter when ice forms.
• Reason: These relate to water's volume increase and density decrease upon freezing, allowing ice to float and providing a habitat for aquatic life in winter.

2. Universal Solvent

• Definitions/Examples:
• dissolves salts and sugars
• helps with biochemical reactions in aquatic environments because many substances can dissolve in it
• can dissolve more substances than another liquid.
• Reason: These describe water's ability to dissolve a wide range of polar and ionic substances, making it a universal solvent.

3. Cohesion and Adhesion

• Definitions/Examples:
• when water molecules stick to other water molecules
• allows water to travel up plants
• when water molecules stick to other polar molecules.
• Reason: Cohesion is the attraction between water molecules (sticking to each other), and adhesion is attraction to other polar molecules (aiding water transport in plants).

4. High specific heat capacity

• Definitions/Examples:
• Water can absorb quite a bit of energy before changing from a liquid to a gas
• Bodies of water do not change temperature as quickly as the air
• Organisms are mostly water and can regulate their body temperatures because of this property
• Water takes a long time to boil.
• Reason: High specific heat means water can absorb/release large amounts of heat with little temperature change, affecting climate, body temperature regulation, and boiling time.

5. Hydrogen Bonds

• Definition/Example:
• bond between the hydrogen atom of one water molecule and the oxygen atom of another molecule
• this property allows water to be a universal solvent, expand when it freezes, absorb a lot of heat, and giving it cohesion and adhesion.
• Reason: Hydrogen bonding between water molecules is the underlying cause of all the other properties (cohesion, adhesion, expansion upon freezing, high specific heat, and solvent properties).

Answer:

1. Expansion upon freezing:

• water expands when it freezes
• ice floats on top of the water
• aquatic organisms can survive in lakes and ponds even in the winter when ice forms.

2. Universal Solvent:

• dissolves salts and sugars
• helps with biochemical reactions in aquatic environments because many substances can dissolve in it
• can dissolve more substances than another liquid.

3. Cohesion and Adhesion:

• when water molecules stick to other water molecules
• allows water to travel up plants
• when water molecules stick to other polar molecules.

4. High specific heat capacity:

• Water can absorb quite a bit of energy before changing from a liquid to a gas
• Bodies of water do not change temperature as quickly as the air
• Organisms are mostly water and can regulate their body temperatures because of this property
• Water takes a long time to boil.

5. Hydrogen Bonds:

• bond between the hydrogen atom of one water molecule and the oxygen atom of another molecule
• this property allows water to be a universal solvent, expand when it freezes, absorb a lot of heat, and giving it cohesion and adhesion.
