Kinetic Molecular Theory

The Kinetic Molecular Theory states that:

• Particles within liquids and gases are moving, but they are not moving within solids.

• Particles within gases are moving, but they are not moving in solids and liquids.

• All matter is made of moving particles.

Which state of matter has the greatest density?

• Solid

• Liquid

• Gas

• They would all have the same density, if they are the same substance.

Which state of matter has the greatest entropy?

• Solid

• Liquid

• Gas

• They would all have the same entropy, if they are the same substance.

Temperature is a direct measure of:

• The density of the particles within a substance.

• The average speed of the particles within a substance.

• How often the particles collide with the walls of their container.

As the temperature of a substance increases:

• The speed, and average kinetic energy of the particles, both increase.

• The speed, and average kinetic energy of the particles, both decrease.

• The speed of the particles increases, but the average kinetic energy of the particles decreases.

• The speed of the particles decreases, but the average kinetic energy of the particles increases.

Absolute Zero is defined as:

• The lowest temperature which can be achieved by scientists.

• The lowest temperature which can be recorded on a thermometer.

• The theoretical temperature at which all particles stop moving.

• The temperature of a cold block of copper.
