Chapter 2 Flashcards
Capillary action is the result of which property of water?
Adhesion
Why is capillary action important for life?
Allows blood to flow to and from the heart, without heeding to the laws of gravity.
Water is referred to as the “universal solvent” because
Its versatility: dues to the inherent polarity of water molecules, H is the solvent in all cells, blood and plant sap.
How does specific heat maintain a livable environment on earth?
Water has a high heat capacity. Heat must be absorbed to break hydrogen bonds, and heat is released when the bonds form. To raise temperature of water, H bonds must be broken.
Failure to maintain the homeostasis of blood can affect the activity of
Enzymes that clot the blood, white blood cells that protect you from disease.
A pH of 0 is
A strong acid
A pH of 14 is a
Strong base
A pH of 7 is
Water
Hydrogen and oxygen atoms in a water molecule are held together by
Polar covalent bonds
The electrons are not shared equally creating a
Polar molecule
The polarity of water allows it to
Dissolve most substances.
The polarity of water is referred to as the
Universal solvent
Water molecules are attracted to other water molecules. This property is called
Cohesion
Hydrogen bonds form between adjacent water molecules because the ???? charged hydrogen end of one water molecule attracts the ???? charged oxygen end of another water molecule.
Positive, negative
Water molecules stick to other materials die to its polar nature. This property is called
Adhesion
