Lesson 1 Kinetic Theory

A hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory is known as

• real gas

• ideal gas

• imaginary gas

• perfect gas

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

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

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

According to the kinetic theory of gases, gas particles

• Do not always move in straight lines

• Have most their volume occupied by empty space

• Attract each other

• Do not always move randomly

The kinetic energy of a gas is dependent on temperature

• True

• False

Energy is lost when particles collide with each other or the walls of the container

• True

• False

The energy of movement is ___.

• potential energy

• kinetic energy

• mechanical energy

The more energy that particles have, the ___ they move.

• slower

• faster

The force of attraction between molecules is ___.

• intermolecular forces

• bridge forces

• chemical bonds

Collisions in which particles transfer all their kinetic energy to other particles are called ___.

• elastic

• inelastic

Which one of these is NOT an Ideal Gas Assumption?

• Gas particles are hard, round spheres.

• Gas particles are strongly attracted to one another.

• Gas particles do not take up space.

• Gas particles collide perfectly elastically.
