Page 1: Introduction to States of Matter
This page introduces the three states of matter and provides basic definitions for solids, liquids, and gases. It then delves into the particle arrangement and movement in each state.
Definition: A solid is a substance or object that is hard/firm rather than a liquid or fluid body.
Definition: A liquid is a substance that can flow freely but has volume, with the consistency of water or oil.
Definition: A gas is a substance or matter that expands freely to occupy the whole of a shape, having no fixed form and volume.
The page explains that in solids, particles are regularly arranged and touch their neighbors, moving only by vibrating. This explains why solids have a fixed shape. In liquids, particles are randomly arranged and move freely over each other, allowing liquids to be poured. In gases, particles are widely spaced apart and move quickly in random directions, filling the space of their container.
Highlight: Understanding the arrangement of particles in solid, liquid and gas is crucial for grasping the fundamental differences between these states of matter.
Page 2: Solids and Liquids in Detail
This page provides an in-depth look at the particle arrangement and behavior in solids and liquids.
For solids:
- Particles are packed together tightly in a neat and ordered arrangement
- Particles are held together strongly, allowing only vibration
- Examples include paper, bricks, wood, metal, and ice
- Solids have a fixed shape and cannot flow like liquids
- Solids expand when heated due to increased particle vibration
Example: The particle arrangement of solid materials like bricks demonstrates why they maintain a fixed shape and cannot be easily compressed.
For liquids:
- Particles are quite close together but move with random motion
- Particles can move around and over each other, allowing liquids to flow and be poured
- Examples include water, oil, and fruit juice
- Liquids cannot usually be compressed or squashed
Vocabulary: Compression refers to the process of squeezing or pressing something into a smaller space.
Highlight: The particle movement of liquid allows it to flow and take the shape of its container, unlike solids.
Page 3: Gases and the Particle Model of Matter
This page focuses on the characteristics of gases and introduces the particle model of matter.
For gases:
- Particles move rapidly in all directions, frequently colliding with each other and the container
- Particles are widely spaced and randomly arranged
- Gases can be easily compressed or squashed
- Examples include air and helium
Example: The particle movement of gas in a balloon allows it to expand and fill the entire space of the balloon.
The particle model of matter:
- Almost everything is made of particles, except for electromagnetic waves like light and X-rays
- A particle is a single piece of matter from an element or compound, too small to be seen with a school microscope
- Particles can be atoms, molecules, or ions
Definition: A model in science is used to help explain scientific concepts. The particle model refers to the diagrams used to represent solids, liquids, and gases.
Year 7 Particles Revision Guide
This comprehensive guide covers the fundamental concepts of particle theory for Year 7 students, focusing on the three states of matter: solids, liquids, and gases. Key points include:
- Definitions and characteristics of solids, liquids, and gases
- Particle arrangement and movement in each state of matter
- Examples of materials in different states
- The particle model of matter and its importance in scientific understanding
Highlight: This guide is an essential resource for students preparing for their Year 7 particles test or studying the particle theory of matter Grade 7.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Best app on earth! no words because it’s too good

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
