Cards

Term
polar molecules
Definition
H2O with opposite charges at different ends
Term
cohesion
Definition
binding alike molecules
Term
adhesion
Definition
attraction of different molecules
Term
surface tension
Definition
measure of how difficult it is to break the surface of a liquid. H2O is high
Term
specific heat
Definition
amount of heat absorbed/lost in 1 g/1 degree Celsius
Term
hydrophilic
Definition
affinity for H2O
Term
hydrophobic
Definition
aversion to H2O; coalesce and form droplets
Term
evaporative cooling
Definition
makes surface cooler in evaporation, loss of molecules with greatest kinetic energy
Term
buffer
Definition
consists of acids and bases and minimizes the changes in pH levels with there is more acid or more base.
Term
organic chemistry
Definition
study of organic compounds
Term
hydrocarbon
Definition
organic molecule with only Hydrogen and Carbon
Term
isomer
Definition
same molecular molecules, but with different structures
Term
structural isomer
Definition
same molecular formulas, different covalent bond arrangements in atoms
Term
geometric isomer
Definition
same molecular and covalent structure, but differ in spatial arrangements in their atoms, owing to the inflexibility of double bonds
Term
enantiomer
Definition
1 of 2 compounds that are mirror images of each other
