States of Matter and Molecular Movement

Front

What are gases and liquids made of?

Back

Gases and liquids are made of molecules or inert atoms that are moving about relative to each other.

Front

How do molecules behave in a liquid?

Back

In a liquid, the molecules are constantly in contact with others.

Front

How do molecules behave in a gas?

Back

In a gas, molecules are widely spaced except when they happen to collide.

Front

How do atoms behave in a solid?

Back

In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.

Front

What can be described and predicted using models of matter?

Back

The changes of state that occur with variations in temperature or pressure can be described and predicted using models of matter.

Front

What happens to molecules when a gas is compressed?

Back

When a gas is compressed, the molecules are forced closer together, increasing the frequency of collisions.

Front

How does temperature affect the behavior of molecules in a liquid?

Back

As temperature increases, the molecules in a liquid move faster, increasing the rate of diffusion.

Front

What is the effect of pressure on the state of matter?

Back

Increasing pressure can force a gas into a liquid state, while decreasing pressure can allow a liquid to become a gas.
