Front (Question)

gas —–> solid

Back (Answer)

deposition

Front (Question)

solid ——–> gas

Back (Answer)

sublimation

Front (Question)

gas ——> liquid

Back (Answer)

condensation

Front (Question)

liquid ——> gas

Back (Answer)

evaporation

Front (Question)

solid ———> liquid

Back (Answer)

melting

Front (Question)

liquid ——> solid

Back (Answer)

freezing

Front (Question)

Are CH bonds polar or nonpolar?

Back (Answer)

nonpolar

Front (Question)

In regards to intermolecular forces, the stronger the force, the _________ the boiling point and the ________ the melting point.

Back (Answer)

higher; higher the stronger the force, the less volatile the matter is

Front (Question)

Hydrophilic molecules _____ water.

Back (Answer)

like Hydrophilic molecules are also lipophobic

#10

Front (Question)

Hydrophobic molecules _____ water

Back (Answer)

fear Hydrophobic molecules are also lipophilic

#11

Front (Question)

C02 has ______ molecular geometry.

Back (Answer)

linear

#12

Front (Question)

T or F: CO2 is polar.

Back (Answer)

False, CO2 is nonpolar

#13

Front (Question)

T or F: N2O is a polar molecule.

Back (Answer)

True.

#14

Front (Question)

Does N2O have bent or linear geometry?

Back (Answer)

linear

#15

Front (Question)

Define surface tension.

Back (Answer)

When a liquid has a high enough attractive force with itself, and a low enough force with the surface, it will exhibit high “surface tension.”

#16

Front (Question)

In regards to capillary action, describe cohesion vs adhesion.

Back (Answer)

Cohesion creates surface tension while adhesion attracts the liquid to the wall of the container. Adhesion > Cohesion

#17

Front (Question)

Greater intermolecular forces result in a _____ volatile liquid and ______ vapor pressure.

Back (Answer)

less; lower

#18

Front (Question)

Does vapor pressure increase or decrease with increasing temperatures?

Back (Answer)

Vapor pressure INCREASES with increasing temperature.

#19

Front (Question)

The boiling point of a liquid happens when the vapor pressure is equal to the….

Back (Answer)

atmospheric pressure (or the pressure it is exposed to, can vary with location)

#20

Front (Question)

Define heat of fusion.

Back (Answer)

Energy required to melt a mole of a material Equation given, no temp in equation.

#21

Front (Question)

Define heat of vaporization.

Back (Answer)

Energy required to boil a mole of a material. Equation given, no temp in equation.

#22

Front (Question)

True of False: heat of vaporization < heat of fusion.

Back (Answer)

False. Heat of vaporization is ALWAYS > heat of fusion for all substances

#23

Front (Question)

Amount of energy required to change the temperature of a substance.

Back (Answer)

Specific heat

#24

Front (Question)

Specific heat of water

Back (Answer)

1 cal/g/°C or 4.18 J/g/°C (because 1 cal = 4.18 J) (it takes 1 calorie to raise the temperature of 1 g, 1°C)
