Unit 3: Intermolecular Forces and Properties

________ are liquid at room temperature and will boil when their IMFs are broken.

________ (LDFs) occur between all molecules and are very weak attractions caused by random electron movements.

________ are opposite charges separated by some distance.

________ requires no excess heat to be added.

________ have very tight- knit molecules and have the strongest IMFs.

The combined ________ is used when moles are held constant.

The ________ (KE) is directly proportional to the temperature.

________ is the rate a gas will escape from a container with microscopic holes from high pressure to low pressure.

Intermolecular forces (IMFs) are the forces in between ________.

Even though ________ is the same for gases at the same temperature, this can not be said for velocity because gas molecules have different masses.

________ are the strongest and are very hard to melt.

The ________ is called a polar covalent bond which also causes a slight partial charge on each atom.

The ________ invalid when the temperature is too low and /or the pressure is too high because the gases become too tightly packed.

________ are usually solids at room temperature.

Gases have the ________ IMFs and have the most spread apart atoms.

________ occur when the positive center of one polar molecule is attracted to the negative end of another polar molecule.

occurs between hydrogen and oxygen, nitrogen, or fluorine

a molecule that has electrical charge

a molecule with no electrical charge; equally shared electrons

the amount of light that cannot get through a colored solution
