KMT Postulates

According to kinetic molecular theory-Gas molecules influence each other only by collision; they exert no other forces on each other.

• True

• False

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

According to the kinetic molecular theory, all collisions between gas molecules are inelastic; all kinetic energy is lost.

• True

• False

Gas particles are in constant, rapid, straight-line ​ (a)   . The temperature is directly proportional to the average ​ (b)   . The hotter the temperature, the ​ (c)   the particles move.
