Water (Bio) Flashcards
What is biochemical
Reaction that occurs inside a living cell, where one molecule is transformed into another.
What is Thermal regulation
Controls body temperature
What is polar because
electrons are shared unequally in the polar covalent bonds between O and H.
What is polar
Different parts of a molecule have opposite charges
Hydrogen bonds form
between different water molecules (H and O)
What are properties of water
Cohesion, Surface tension, Adhesion, Capillary action, High heat, less dense, Universal Solvent, and Neutral pH
What is cohesion
Attraction between the same type of molecules
What is surface tension
water molecules on the surface are more strongly attracted to each other and form a “skin” that can resist outside forces
What is Adhesion
molecules of one
type is attracted to different
type of molecule
What is capillary action
Movement of water up a narrow
tube against gravity
What is heat capacity
the amount
of energy needed to raise
a substance’s temperature
by making its molecules
move faster
What is thermal regulation
an organism’s ability to control its body
temperature
What is homeostasis
rapid changes in body
temperature when the environment
changes
What is heat of vaporization
the
amount of energy needed to
turn a liquid into a gas
What has a ___ heat of vaporization
High
