Chapter 6 Gas, Liquid and Solid Flashcards
Atmosphere (atm)
A pressure unit
Atmospheric Pressure
The pressure exerted by the atmosphere
Boyle’s Law
A gas law stating that the pressure of a gas is inversely related to the volume when temperature and moles of the gas do not change; that is if volume decreases, pressure increases.
Charles’ Law
A gas law stating that the volume of a gas changes directly with a change in Kelvin temperature when pressure and moles of the gas do not change.
Combined gas law
A relationship that combines several gas laws relating pressure, volume and temperature. P1V1/T1=P2V2/T2
Direct relationship
A relationship in which two properties increase or decrease together.
Ideal gas law
A law that combines the four measured properties of a gas in the equation. PV=nRT
Inverse relationship
A relationship in which two properties change in opposite directions.
Kinetic molecular theory of gases
A model used to explain the behavior of gases.
Pressure
The force exerted by gas particles that hit the walls of container.
Dipole-dipole attractions
Attractive forces between oppositely charged ends of polar molecules.
Gas
A state of matter characterized by no definite shape or volume. Particles in a gas move rapidly.
Hydrogen bonding
The attraction between a partially positive H and strongly electronegative atom of F, O or N. It is the strongest IMF.
IMF
Intermolecular Forces. The attraction between molecules.
Liquid
A state of matter that takes the shape of its container but has a definite volume.
