How Do Particles Behave and What Are Pure and Impure Substances?

Energy Stores and Transfers
This page focuses on different types of energy stores and how energy is transferred between them, providing essential information for understanding energy stores and transfers in science GCSE.
Types of Energy Stores The page lists and explains various energy stores:
- Thermal Energy Store
Definition: Thermal energy is stored in all objects, with higher temperatures indicating more stored energy.
- Kinetic Energy Store
Vocabulary: Kinetic energy is associated with movement.
- Chemical Energy Store
Example: Food and fuel are examples of chemical energy stores that release energy through chemical reactions.
- Gravitational Potential Energy Store
Definition: This is the energy stored in objects within a gravitational field, capable of being released when the object falls.
- Elastic Potential Energy Store
Example: Stretched springs store elastic potential energy.
- Electrostatic Energy Store
Definition: Energy stored in electric charges that attract or repel each other.
- Magnetic Energy Store
Example: Magnets that attract or repel each other store magnetic energy.
Energy Transfers Between Stores The page illustrates several examples of energy transfers:
- Dropping an Object
Highlight: Energy transfers from gravitational potential store to kinetic store.
- Burning Fuel
Example: Chemical energy store in fuel transfers to thermal energy store in surroundings.
- Releasing a Stretched Object
Highlight: Elastic potential energy store transfers to kinetic energy store.
- Using a Circuit to Move a Motor
Example: Chemical energy store in a battery transfers to kinetic energy store in the motor and thermal energy store in the surroundings.
Highlight: Understanding these energy stores and transfers examples is crucial for GCSE Physics and provides a foundation for more complex energy concepts.
Particles and States of Matter
This page delves into the behavior of particles in different states of matter and explores the processes of state changes. It also introduces the concepts of dissolving and pressure.
Solid State In solids, particles vibrate in fixed positions due to strong forces of attraction.
Highlight: Solid particles have limited movement and are held tightly together.
Liquid State Liquid particles flow and move past each other with more freedom than solids.
Vocabulary: Liquid particles have weaker forces of attraction compared to solids, allowing for greater movement.
Gas State Gas particles move freely with weak forces of attraction between them.
Example: The movement of particles in solid, liquid and gas states can be visualized as: solid , liquid , and gas .
Changes of State The page illustrates various state changes:
- Melting: Solid to liquid
- Freezing: Liquid to solid
- Boiling/Evaporating: Liquid to gas
- Condensing: Gas to liquid
Definition: Particle arrangement of liquid is less ordered than solids but more constrained than gases.
Dissolving The process of dissolving is explained, introducing terms like solute, solvent, and solution.
Highlight: Hot water dissolves solutes faster due to increased particle movement.
Pressure Pressure is related to temperature and volume. Increasing temperature or reducing volume leads to increased pressure.
Example: In a closed container, heating a gas or reducing its volume will increase the pressure as particles collide more frequently with the container walls.
Pure and Impure Substances The page concludes by differentiating between pure and impure substances.
Definition: Pure substances have fixed melting and boiling points, while impure substances have a range of melting and boiling points.

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!

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
