EXAM 1 Flashcards
A liquid’s resistance to flowing
Viscosity
The intermolecular forces between the molecules of the liquid
Cohesive forces
Interactions between the liquid and a solid surface
Adhesive forces
Energy required to increase the surface area of a liquid.
Surface tension
A liquid flows on a material Ex. Paper towels
Capillary
Unequal sharing of electrons
Polar covalent bonds
Amount of heat that most the absorbed or lost before it actually changes temperature. (water takes a long time to boil)
Specific Heat
The cooling of a surface occurs when the liquid evaporates (fire walking)
Heat of Vaporization
If something is more dense than water is going to sink (water is more dense as a liquid)
Density
A liquid that dissolves a particle
Solvent
(the thing that dissolves) Particle or liquid that gets dissolved in the solvent
Solute
Will dissolve in water because water is polar
Polar solutes
Water is?
POLAR
A measure of how difficult it is to stretch or break the surface of a liquid (insects on water)
Surface tension
Very weak bonds; occur when a hydrogen atom in one molecule is attracted to the electrostatic atom in another molecule.
Hydrogen bonds
