IMF/Gas Laws

IMF

100

Which has higher LDF and why?

CF₄ or CI₄

CI₄

increased MW

200

Can CO₂ H bond? Why or why not?

NO

no hydrogen directly linked to hydrogen

300

Which IMF's are found in HF?

LDF and H bonding

400

Which IMF's are found in CH₃F?

LDF and dipole-dipole

500

How does presence of intermolecular forces influence boiling point?

stronger IMF--> increases BP

600

CH₃Cl

What IMF's are present?

LDF

Dipole dipole

Gas Properties

100

High temp and low pressure allow for gases to behave in this way...

ideally

200

High pressure will cause a gas to behave in this way

like a real gas

300

What is Charles' Law?

V1/T1 = V2/T2

400

This gas law states that increasing pressure will decrease volume (if other measurements are held constant).

Boyle

500

How can you change the kinetic energy of gas molecules?

change temperature

600

What can be said about volume of a REAL gas?

It is not negligible compared to the container volume

Mixed Review

100

How is vapor pressure influenced by IMF strength?

stronger IMF's reduce vapor pressure

200

Which gas will effuse first?

CH₄ or Cl₂?

CH₄

300

What units should be used for volume in the ideal gas law?

volume

400

How do the volumes of real gases compare to those of ideal?

greater than

can't ignore due to IMF's creating a non-negligible volume

500

Why would a real gas have a pressure lower than predicted?

IMF's reduces # of collisions with container walls

Nana

Grab Bag

100

Pop up trivia: This Christmas movie features the Heat Miser

The Year Without a Santa Claus

200

Why are phase changes shown as plateaus in heating curves?

because energy put in is used to break IMF's / it doesn't elevate temperature

Christmas Vacation

400

Which requires more energy and why: fusion or vaporization?

vaporization; all IMF's overcome

The Grinch

600

What is it called when a substance changes from a solid to a gas?

sublimation
