Study the diagram and carefully read the description below the diagram. Gases have no definite shape or volume. Instead, they take the shape of their container. The particles of a gas spread out within the available space. Which diagram illustrates gas particles?

• Diagram A illustrates gas particles.

• Diagram B illustrates gas particles

• Diagram C illustrates gas particles.

• None of these illustrates gas particles.

The particles in a gas are...

• loose and have high energy

• tightly packed and have very little energy

• move freely and have lots of energy

• I dont know Ms. Turner, I didnt take notes

Gases have...

• A definite shape and volume
