Question

assignment

1. page 8 of your text shows the various states of water. using your knowledge of matter as made up of particles, use the information on page 8 to complete the following graphic organizer.

behavior of particles (water molecules)\tgas (water vapor)\tliquid (water)\tsolid (ice)
how close are the particles
compare the movement of the particles
describe the attractive forces between the particles
what else did you notice?

Explanation:

Step1: Determine particle - closeness

In gas (water vapor), particles are far apart. In liquid (water), particles are closer than in gas but can still move around each other. In solid (ice), particles are very close and in a fixed position.

Step2: Analyze particle movement

In gas, particles move freely and rapidly in all directions. In liquid, particles move more slowly than in gas and slide past one another. In solid, particles vibrate in place but do not move from their fixed positions.

Step3: Evaluate attractive forces

In gas, attractive forces between particles are very weak. In liquid, attractive forces are stronger than in gas but still allow for some movement. In solid, attractive forces are strong, holding particles in place.

Step4: Additional observations

Gases have no definite shape or volume and expand to fill their container. Liquids have a definite volume but take the shape of their container. Solids have a definite shape and volume.

Answer:

Behavior Of Particles (water Molecules)	Gas (Water Vapor)	Liquid (Water)	Solid (Ice)
Compare the movement of the particles	Move freely and rapidly in all directions	Move more slowly, slide past one another	Vibrate in place, no movement from fixed position
Describe the attractive forces between the particles	Very weak	Stronger than gas, allows some movement	Strong, holds particles in place
What else did you notice?	No definite shape or volume, expands to fill container	Definite volume, takes shape of container	Definite shape and volume
