#1
正面 (问题)

Intermolecular forces

背面 (解答)

Forces that attract molecules to each other + attracting - Responsible for state of matter at room temperature

#2
正面 (问题)

Electrostatic attraction

背面 (解答)

Intermolecular forces

#3
正面 (问题)

Dipole

背面 (解答)

Molecule with a polar covalent bond (One part is charged +, one part is charged -) Temporary because electrons always moving

#4
正面 (问题)

Hydrogen bonding (IMF)

背面 (解答)

Strongest Attraction between molecules containing very strong dipoles In molecules containing hydrogen bonded to a very electronegative element (H2O, NH3, HF)

#5
正面 (问题)

Dipole-dipole bonding (IMF)

背面 (解答)

Middle strength Attraction between two dipole molecules In all dipoles when they get close to each other (H2S, HCl, HBr)

#6
正面 (问题)

(London) Dispersion Forces (IMF)

背面 (解答)

Weakest Attraction between two non polar molecules In all molecules, but major force of attraction in two non polar molecules (CO2, Br2, I2)

#7
正面 (问题)

Substance with ______ IMF will probably be a gas at room temperature

背面 (解答)

Weak

#8
正面 (问题)

Substance with ________ IMF will probably be solid or liquid at room temperature

背面 (解答)

Strong

#9
正面 (问题)

Vapor Pressure

背面 (解答)

Measured when a liquid is placed in a sealed container at measured temperature and allowed to evaporate. Air above liquid becomes saturated with vapor.

#10
正面 (问题)

Equilibrium

背面 (解答)

For every molecule that evaporates, one condenses

#11
正面 (问题)

When do liquids boil

背面 (解答)

When the vapor pressure = atmosphere pressure

#12
正面 (问题)

As temperature of a liquid increases, vapor pressure above the liquid ______

背面 (解答)

Increases

#13
正面 (问题)

When there is a lower atmospheric pressure, the vapor pressure needed to boil is _______ so it boils at a _______ temperature

背面 (解答)

Lower

#14
正面 (问题)

Viscosity

背面 (解答)

A fluids resistance to flow

#15
正面 (问题)

Surface tension

背面 (解答)

The intermolecular attraction between the molecules at the surface of a liquid

#16
正面 (问题)

Sublimation

背面 (解答)

Solid > gas

#17
正面 (问题)

Deposition

背面 (解答)

Gas > solid

#18
正面 (问题)

Vaporization

背面 (解答)

Evaporation Boiling (Liquid > gas)

#19
正面 (问题)

Triple point

背面 (解答)

Point at which all three states of matter coexist

#20
正面 (问题)

Critical point

背面 (解答)

Point beyond which only gas is possible (supercritical fluid)

#21
正面 (问题)

Normal freezing point

背面 (解答)

At 1 ATM pressure, point at which melt/freeze

#22
正面 (问题)

Normal boiling point

背面 (解答)

At 1 ATM pressure, point at which boil/condense

#23

Solution

背面 (解答)

Evenly mixed throughout Contains solute and solvent

#24
正面 (问题)

Solvent

背面 (解答)

Substance in greatest amount in a solution
