States of Matter, Atoms, and PT Intro

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

• are spread far apart

• move freely but are in 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

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 something takes up is its

• volume

• mass

• pressure

• density

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

In a(n) (a)   , the particles are packed closely together, but they can move past each other freely.

The characteristic temperature at which a pure solid changes to a liquid is its (a)   point.
