# The Particle Model of Matter

*Time: 15 min. 6 questions.*

## Instructions

Answer all six questions. Use what you know about how particles behave in solids, liquids, and gases. For short-answer questions, write one or two sentences. For multiple choice, circle the letter of the best answer.

## Questions

1. Which statement best describes how particles are arranged in a solid? ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475))

A) Particles are far apart and moving in all directions.
B) Particles are close together and vibrate in place.
C) Particles are separated by spaces and can slide past each other.
D) Particles have no spaces between them and do not move at all.

2. In the particle model of matter, what are the three main ideas? Write them as a short list. ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475))

3. True or False: In a gas, the attractive forces between particles are stronger than in a liquid. ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475))

4. A block of wood has a mass of 240 grams. Write the mass using the correct SI unit abbreviation. ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479))

## Answer Key

1. **B) Particles are close together and vibrate in place.** In solids, particles are held tightly in place by strong attractive forces and can only vibrate, not move freely.

2. **All matter is made up of small particles; particles of matter are always moving; particles of matter have spaces between them.** These three ideas form the foundation of the particle model of matter ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)).

3. **False.** Attractive forces between particles are weakest in gases and strongest in solids, so the statement reverses the correct relationship ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)).

4. **240 g.** Grams (g) is the correct SI unit abbreviation for measuring mass ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36479)).

5. **In a liquid, particles can slide past each other but stay close together with spaces between them. In a gas, particles move constantly in all directions and are separated by large spaces.** This contrast shows how particle movement relates to the state of matter ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)).

6. **C) Gas.** Attractive forces are weakest in gases because particles are far apart and moving freely in all directions ([Knowledge](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/36475)).
