State of Matter and Phase Changes

Air, the gas we are most familiar with, consists of

• a mixture of several different kinds of gases.

• gas particles of only one kind.

• particles of only nonreactive gases.

• a single compound made up of several gases.

The intermolecular force of attraction between temporary dipoles of non-polar particles is called a(n)

• dispersion force.

• polarization force.

• induction force.

• dipole-dipole force.

The direct change of a substance from a solid to a gas is called

• solidification.

• sublimation.

• condensation.

• evaporation.

Amorphous solids, because of their disordered arrangement of particles and the associated porperties, are often more appropriately labeled

• hydrated solids.

• imperfect solids

• supercooled liquids.

• semisolids

Those liquids that have the greatest surface tension would likely have

• weak forces of attraction.

• very large repulsive forces.

• hydrogen bonding.

• London forces.

When a gas is heated,

• all of the absorbed energy is converted to potential enery.

• all of the absorbed energy is converted to kinetic energy.

• some of the absorbed energy is converted to potential energy and some is converted to kinetic energy.

• none of the energy is converted to kinetic energy.

Liquids and solids are referred to as the condensed states of matter because they

• are less strongly bonded than gases.

• have their water molecules removed.

• are lower in energy than gases

• have greater densities than gases.

If the states of matter are arranged in order of increasing disorder, the arrangement would be

• liquid, solid, gas.

• gas, liquid, solid.

• gas, solid, liquid.

• solid, liquid, gas.

In addition to hydrogen, what other atoms are most common in compounds that have hydrogen bonds?

• fluorine

• nitrogen

• oxygen

• any of these.

The meniscus in a test tube of water demonstrates the unequal effect intermolecular forces have on all particles in a liquid. The force that causes the meniscus is

• cohesion.

• adhesion.

• hydrogen bonding.

• all of the above.
