According to the kinetic molecular theory, the volume actually occupied by the molecules of a gas is negligibly small; the vast majority of the volume of the gas is empty space through which the gas molecules are moving.

• True

• False

In the KMT, pressure is the force exerted against the wall of a container by the continual collision of molecules against it.

• True

• False

The total kinetic energy of a collection of gas molecules is inversely proportional to the absolute temperature of the gas.

• True

• False

The first postulate of the KMT is that all matter is made up of

• tiny particles

• molecules

• cells

• mass

According the KMT, the particles are in

• different states

• organized patterns

• constant motion

• various containers

According to the KMT, increasing the temperature of particles will

• give off energy

• increase motion

• decrease volume

• increase pressure

• Gas particles are elastic and do not attract each other.
• The kinetic energy of gas is dependent on temperature 
• Energy is not lost when gas particles collide with each other or with the walls of the container.
• All of the above
