Chemistry Chapter 10 Practice Test

According to the kinetic-molecular theory, particles of matter

• are in constant motion.
• have different shapes.
• have different colors.
• are always fluid.

According to the kinetic-molecular theory, gases condense into liquids because of

• gravity.
• atmospheric pressure.
• forces between molecules.
• elastic collisions.

The kinetic-molecular theory explains the behavior of

• gases only.
• solids and liquids only.
• liquids and gases only.
• solids, liquids, and gases.

Which process can be explained by the kinetic-molecular theory?

• combustion
• oxidation
• condensation
• displacement reactions

According to the kinetic-molecular theory, which substances are made of particles?

• gases only
• liquids only
• all matter
• all matter except solids

The kinetic-molecular theory explains the properties of solids, liquids, and gases in terms of the energy of the particles and

• gravitational forces.
• the forces that act between the particles.
• diffusion.
• the mass of the particles.

According to the kinetic-molecular theory, particles of matter are in motion in

• gases only.
• gases and liquids only.
• solids, liquids, and gases.
• solids only.

An ideal gas is a hypothetical gas

• not made of particles.
• that conforms to all of the assumptions of the kinetic theory.
• whose particles have zero mass.
• made of motionless particles.

Unlike in an ideal gas, in a real gas

• all particles move in the same direction.
• all particles have the same kinetic energy.
• the particles cannot diffuse.
• the particles exert attractive forces on each other.

A real gas

• does not obey all the assumptions of the kinetic-molecular theory.
• consists of particles that do not occupy space.
• cannot be condensed.
• cannot be produced in scientific laboratories.
