Gases

• fill the entire container, and no definite volume

• take the shape of the container and have definite volume

• have definite shape and volume

• are cylindrical in shape and have no definite volume

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.
