PS_Chapter03_Review

In which phase are particles generally the closest?

• solid

• liquid

• gas

• plasma

Which is the most common property of all liquids?

• Liquids have a definite shape

• Liquids have a definite volume

• Liquids conduct electricity

• Liquids are transparent

In which phase of matter are the attractive forces between particles strongest?

• solid

• liquid

• gas

• vapor

The diagrams below show the same amount (50 mL) of the same liquid in three differently shaped containers.

The diagrams show that the liquid phase has

• no definite volume and no definite shape

• no definite volume but definite shape

• definite volume and definite shape

• definite volume but no definite shape

Attractive forces between particles are greatest when their kinetic energies are

• high and the distance between particles is large

• high and the distance between particles is small

• low and the distance between particles is large

• low and the distance between particles is small

Which statement correctly describes a sample of gas confined in a sealed container?

• It always has a definite volume, and it takes the shape of the container.

• It takes the shape and the volume of any container in which it is confined.

• It has a crystalline structure.

• It consists of particles arranged in a regular geometric pattern.

As the volume of an gas is increased at constant temperature, the pressure exerted by the gas:

• decreases

• increases

• remains the same

• not enough information is provided

As the temperature of a constant volume of a gas is increased, its pressure will:

• decrease

• increase

• remain the same

• not enough information is provided

A can was filled with crushed ice, sealed, and massed. The ice was melted by slowly warming the can and its contents. No water vapor escaped and no air entered the can.

If the can is then massed again after the ice has melted, what is the best prediction of the mass?

• The mass would be the same.

• The mass would be more.

• The mass would be less.

• It is impossible to predict without more information.

Base your answer to the question below on whether the following example has kinetic energy, potential energy, both or neither.

• kinetic energy

• potential energy

• both

• neither
