• 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

• density and extention of interactions

• temperature and freedom of motion

• freedom of motion and extent of interactions

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

What does increasing the temperatureof a solid lead to?

• increased mass of particles

• decreased space between particles

• decreased velocity of particles

• increased velocity of particles

What is happening when a solid is becoming a liquid?

• The particles decrease in motion, collapsing the organized structure.

• The increased movement of particles pushes them completely out of position, collapsing the organized structure.

• The particles increase in motion, causing the organized structure to flatten into a smaller shape.

• A particle party!

How doe the particles in a liquid 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.

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.
