Chem B: Unit 6: States of Matter

According to the kinetic-molecular theory, particles of a gas

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

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
• mass of the particles

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.

The particles in a liquid are usually

• closer together and lower in energy than those in a solid.
• farther apart and higher in energy than those in a gas.
• closer together and lower in energy than those in a gas.
• farther apart and lower in energy than those in a solid.

Particles within a solid

• do not move.
• vibrate about fixed positions.
• move about freely.
• exchange positions easily.

At its triple point, water can

• have only three pressure values.
• exist in equilibrium in three different phases.
• only be present as vapor.
• exist only as a solid.

Before boiling, the temperature of a liquid

• remains constant.
• decreases
• increases.
• approaches water's boiling point.

Sublimation is

• when solid turns into gas
• when gas turns into plasma
• when liquid turns into gas
• when gas turns into solid
