Chem Unit 8 Test Vocab Flashcards
Chemical bond
A connection between two surfaces or objects that have been joined together.
Intermolecular forces
The forces that hold molecules together.
Indip-indip
Electrons moving randomly around the nuclei of the atoms in a molecule.
Dip-dip
The partially negative side of one dipole is attracted to the partially positive side of a neighboring dipole.
Hydrogen bonding
When molecules are so polar and the dipole-dipole interactions are very strong.
Dipole
Polar molecules.
Viscosity
When a liquid flows, its molecules move past each other. A fluid with low viscosity flows easily, while a highly viscous one is thick and gooey.
Boiling point
The more heat, the faster the molecules move.
Melting point
The specific temperature at which the heat energy overcomes the IMFs.
Kinetic energy
Energy in motion.
Potential energy
The energy based on the forces acting on it.
Solid to liquid
Melting
Liquid to solid
Freezing
Liquid to gas
Boiling
Gas to liquid
Condensation
