4.5 Study Guide Flashcards
What is a solvent?
It is a substance that dissolves other substances.
What is cohesion?
It is H bonding between H2O molecules.
What is heat of vaporization?
It is the energy it takes for 1 gram of water to evaporate. To become water vapor, polar bonds must be completey broken.
What are the five properties of water?
They are:
-Cohesion & Adhesion
-Water is the solvent of life
- Ice is less dense than liquid water
-High Specific Heat
- Heat of vaporization
Examples of why each property is important to living things.
They are important bevuase it needed for survival of organisms like for example cohesion and adhesion is needed for plant survival.
Explain how water’s polarity or ability to make hydrogen bonds gives it each property.
Water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds.
