THE PROPERTIES OF WATER Flashcards
ALL LIVIGN THINGS MUST HAVE A SUPPLY OF ________________ TO LIVE AND FULLY FUNCTION.
Water
WATER IS ESSENTIAL TO MANY..
Chemical reactions
What percentage of water is the typical human body?
60-70%
WHAT IS A POLAR MOLECULE?
A polar molecule has an unequal distribution of charge. (Remember covalent bonds.)
HOW MANY HYDROGEN BONDS IS WATER CAPABLE OF FORMING?
4
WHAT IS THE ATTRACTION BETWEEN WATER MOLECULES CALLED?
Cohesion
COHESION CAUSES
Surface Tension
THE STRONG ATTRACTION MEANS IT TAKES A LOF OF ____________ TO SEPARATE WATER MOLECULES FROM EACH OTHER TO FORM WATER VAPOR. ALSO REFERRED TO AS WATER’S ___________ HEAT OF VAPORIZATION.
Heat
SURFACE TENSION CAUSES WATER A RELATIVELY HIGH ____________ (100c) which allows it to exist in the liquid state of the Earth’s most surface.
Boiling Point
COHESION IS ALSO RELATED TO ANOTHER PROPERTY OF WATER CALLED?
Adhesion of Attraction. (Between water molecules and other molecules.)
THE HYDROGEN BINDING BETWEEN THE WATER MOLECULES AFFECTS THE ________________________ OF WATER.
Density
THE HYDROGEN BONDING BETWEEN WATER MOLECULES ALLOWS WATER TO ABSORB AND STORE HEAT MAKING IT AN EXCELLENT TEMPERATURE
Buffer
WATER HAS THREE STAGES,
Solid, Liquid, Gas.
POLARITY GIVES WATER ITS ROLE AS A _____________ OR _________________ IN MANY CHEMICAL REACTIONS.
Reactant, Product
POLARITY ALSO GIVES WATER ITS IMPORTANT PROPERTY OF BEING AN EXCELLENT ____________.
Solvent
A _______________ IS A MIXTURE OF TWO OR MORE KINDS OF MOLECULES, ATOMS, OR IONS THAT IS HOMOGENOUS THROUGHOUT.
SOLUTION
A _______________ IS A SUBSTANCE THAT DISSOLVES OTHER SUBSTANCES.
SOLVENT
A ____________ IS THE SUBSTANCE BEING DISSOLVED.
SOLUTE
HYDROPHILIC
Water-loving. Refers to the polar substances that will interact with water.
HYDROPHOBIC
Water-fearing. Refers to non polar molecules such as fats and oils that do not interact with water.
IS WATER ORGANIC OR INORGANIC?
Inorganic
