States of Matter

A solid is a state of matter that has a(n)

• indefinite volume and indefinite shape

• definite volume and a definite shape

• definite volume and an indefinite shape

• indefinite volume and a definite shape

In which state of matter are particles packed tightly together in fixed positions?

• gas 
• solid
• liquid
• plasma

Particles of a liquid

• are tightly packed together and stay in a fixed position
• have no viscosity
• decrease in volume with increasing temperature
• are free to move in a container but are in close contact with one another

In which state of matter do particles spread apart and fill all the space available to them? 

• crystal
• liquid
• gas
• solid

The change from a  liquid to solid, or the reverse of melting, is called

• condensation
• boiling
• sublimation
• freezing

The freezing point of water is the same as its

• melting point

• boiling point

• sublimation point

• evaporation point

An uncovered pot of soup is simmering on a stove, and there are water droplets on the wall above the back of the stove. What sequence can you infer has occurred?

• melting, then boiling

• freezing, then thawing

• vaporization, then condensation

• condensation, then vaporization

The amount of space that a gas takes up is its

• volume
• mass
• pressure
• density

Which state of matter undergoes changes in volume most easily?

• solid
• liquid
• gas
• frozen

During the process of sublimation

• a solid turns directly into a gas
• a solid turns into a liquid
• a gas turns directly into a solid 
•  a liquid turns into a gas
