KMT OF GASES

______refers to the energy of an object in motion

What will happen to the size of a balloon if you will place it inside the freezer?

• decrease

• increase

• remains the same

In which state of matter are the particles moving the least random?

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Gas particles move around in an orderly manner.

• The temperature of a gas depends on the average kinetic energy of the gas particles.

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

The particles are in random motion. The collisions of the particles with the walls of the container are the cause of the pressure exerted by the gas.

• TRUE

• FALSE

Liquids can change their volume depending on the container

• TRUE

• FALSE

The average kinetic energy of a collection of gas particles is assumed to be inversely proportional to the Kelvin temperature of the gas.

• TRUE

• FALSE

The bombardment of the particles against the walls of the vessel causes gas pressure

• TRUE

• FALSE

Gases apply pressure in all directions (a good sample is a balloon).

• TRUE

• FALSE

All matter has mass and takes up space.

• TRUE

• FALSE
