Module 4: Kinetic Molecular Theory

Gas particles are very far apart with one another and that we cannot see these

particles. We can just feel them. Gases behave differently from solids and liquids.

• TRUE

• FALSE

• MAYBE

Ludwig Boltzmann and James Clerk

Maxwell found that the physical properties of gases could be explained in terms of

motion of the individual molecules.

• TRUE

• FALSE

• MAYBE

Fill in the blank.

The assumptions of this theory are

the following:

Gases are made up of tiny particles called _______________.

• matter

• cell

• molecules

• atom

These molecules are

separated from each other by distances far greater than their dimensions, which

means that they possess mass but negligible volume. This explains why gases have

low densities and are highly compressible.

• TRUE

• FALSE

• MAYBE

Gas molecules are in constant __________ in random directions and they frequently

collide with one another.

• Pressure

• temperature

• volume

• motion

The constant motion of the particles enables gases to easily

occupy all available space. This is the reason why gases expand, diffuse and effuse.

• TRUE

• FALSE

• MAYBE

The average kinetic energy of the molecules is proportional to the temperature of

gas in ___________.

• CELCIUS

• FHARENHEIT

• KELVIN

• MOLE

The Kinetic Molecular Theory provides a molecular interpretation of temperature. The higher the ______________, the more energetic the motion is.

• NUMBER OF GAS

• VOLUME

• PRESSURE

• TEMPERATURE

Assumption 3.

There is a negligible attractive or repulsive force between or among gas molecules.

• TRUE

• FALSE

• MAYBE

Since molecules are separated by large distances in assumption 1, gases can

easily be compressed to occupy smaller volume.

Which is the best example in applying gas law?
