Unit 6: Gas Laws And States Of Matter Flashcards
Adhesion
Bonding between two substances (water clinging to a plastic water bottle)
Definition of triple point
The point where all phase changes are present and are therefore at equilibrium
Ideal Gas Law
Pv=nrt
Ranking of intermolecular forces from strongest to weakest
Hydrogen-bonding
Dipole-dipole
Dispersion
Intermolecular definition
Bonds that hold together molecules of the same type
Intramolecular definition
Holds the atoms of molecules together
Ranking of strongest to weakest for intramolecular forces
Ionic
Polar
Non polar
Definition of viscosity
A measure of resistance of a liquid to flow
Factors that effect viscosity
Stronger intermolecular forces- greater viscosity
Larger and longer molecules will form more viscous solutions
Decreases with temperature
Gay-Lussac Law Equation
P/T= P/T
Charles Law Equation
V/T=V/T
Boyle Law Equation
PV=PV
Combined Gas Equation
PV/T=PV/T
When does dispersion occur
In a non polar bond (when the central atom has a lone pair of electrons
What atoms form a hydrogen bond
Hydrogen with either Florine, nitrogen or oxygen
When do dipole dipole bonds occur
In intermolecular bonds within polar bonds
Ideal gas
Gases that behave according to kinetic molecular theory
Diffusion definition
The process of a substance spreading out equally over the given space (the smell of fresh cookies spreading through a house)
Effusion definition
Passage of gas through a tiny hole
Avagadros hypothesis
Equal volumes of gases at the same temperature and pressure contain equal number of particles
CONVERSIONS
1atm=101kPa=14.7psi=7.60x10^2torr
Fahrenheit conversion
F=1.8(c)+32
Cohesion
Bonding within a substance
