Ideal Gas Laws Questions?

Check all of the following that are not postulates in the Kinetic Molecular Theory of Gases, as presented in the textbook. You should check anywhere from one to six boxes.

There are no attractive forces between the particles

The average kinetic energy is proportional to the number of moles of particles

The pressure is proportional to the mass of the particles

The average kinetic energy of the particles is proportional to the absolute temperature

The volume of the particles is negligible compared to the volume of the container

The particles undergo constant, random motion

Check all of the following statememts that are true. (You should check anywhere from one to three boxes.)

none of these statements are true

dipolar forces arise from temporary induced dipoles on neighboring atoms or molecules

dispersion forces arise from the transfer of electrons from one molecule to the other

hydrogen bonding arises between hydrogen atoms on neighboring molecules

Check all of the statements that are true. (Read them carefully.) You should check anywhere from one to three boxes.

none of these statements are true

compounds with hydrogen bonding usually have lower boiling points than similar compounds without hydrogen bonding

non-polar compounds usually have higher boiling points than polar compounds of similar mass

lighter compounds usually have greater dispersion forces than heavier compounds
