KMT

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

NGSS.HS-PS3-2

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

• tiny particles

• molecules

• cells

• mass

In a solid, what keeps each particle trapped in the same small volume and with the same surrounding particles.

• strong attractions between particles

• ionic bonds

• lack of particle motion

• low temperatures

NGSS.HS-PS1-3

How doe the particles in a gas behave?

• Neatly organized without any movement.

• Move around trapped in a small volume and with the same surrounding particles.

• Move fast enough to break attractions and pushing other particles out of the way.

• Move freely in a straight line until they collide with another particle.

NGSS.MS-PS3-4

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

• 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

Ideal gases (best conditions) are light molecules such as hydrogen and helium. Heavier gases do not follow this rule.

• True

• False

Real gases have attraction to other gas molecules which is opposite of the kinetic molecular theory. This way they can have a chemical reaction with each other.

• True

• False
