Year 7 End of Year Exam - Particles
This Year 7 particles revision guide provides a comprehensive overview of the particle theory of matter, focusing on the three states of matter: solids, liquids, and gases. It explains the arrangement and movement of particles in each state, using clear examples and illustrations to aid understanding. The guide is an excellent resource for students preparing for their Year 7 Chemistry test or studying the particle theory of matter Grade 7.

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.
This page provides an in-depth look at the particle arrangement and behavior in solids and liquids.
For solids:
Example: The particle arrangement of solid materials like bricks demonstrates why they maintain a fixed shape and cannot be easily compressed.
For liquids:
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.
This page focuses on the characteristics of gases and introduces the particle model of matter.
For gases:
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:
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.

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.

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!

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.
