Cindy wrote the following phrase to describe the movement of particles in a state of matter.

"Tennis balls are neutral particles, far away from each other and moving at fast speeds."

Which state of matter did Cindy most likely describe?

Gas

Liquid

Plasma

Solid

The gas particles are the ones that move more freely at high speeds because they are well separated. The liquid particles are close together with no regular arrangement but can vibrate and move but less that gas. solid's are tightly packed in a pattern, only vibrate and don't move more that that.

The answer is gas.
