kinetic molecular 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.

If a gas has the same temperature throughout, which gas molecule has the highest average velocity?

• O₂

• H₂O

• H₂

• Xe

Which condition is necessary for most gases to behave nearly ideally?

• high pressure

• high temperature

• low compressibility

• low expansion

Which of the following is not one of the assumptions of the kinetic molecular theory for ideal gases?

• The particles attract and then repel each other.

• The collisions between particles are elastic

• The particles are in constant random motion.

• The particle size is very small compared to the space between the particles.

How are pressure and temperature related?

• Directly

• Indirectly

• They aren't related

Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

The energy of movement is ___.

• potential energy

• kinetic energy

• mechanical energy

The pressure exerted by a gas does not depend on

• temperature.

• volume.

• number of moles present.

• the identity of the gas.
