States and Changes in Matter

A substances state of matter is determined by

• the chemicals in the substance
• the speed of the particles and the attraction between them
• the size of the particles
• the amount of matter in the substance

The atoms and molecules in each state of matter

• are attracted to one another
• are constantly moving
• move faster at higher temperatures
• All of these answers are correct

Why does a liquid take the shape of the container it is poured in but an ice cube does not?

• Because the molecules of liquid water are softer than the molecules of a solid
• Because the molecules of a liquid are smaller than the particles of a solid
• Because the molecules of the liquid are moving but the molecules of the solid are not
• Because the molecules of the liquid can easily slide past each other but the particles of a solid cannot

In a laboratory experiment, De'andre observed water as it vaporized, froze, melted, and condensed. What conclusion can be made about his experiment? 

• He observed different changes of state.
• Each of these processes happened at different temperatures.
• All off the changes required energy to absorbed.
• All of the changes required energy to be released
