A comprehensive guide to energy transfer and states of matter... Show more
This section delves deeper into the mechanisms of heat transfer and their practical applications in building design and insulation.
Definition: Thermal conductors are materials through which energy transfers easily, typically metals.
Example: Houses in cold climates utilize insulation and heating systems, while houses in hot climates often feature white paint to reflect infrared radiation.
Highlight: Vacuum flasks demonstrate multiple heat transfer prevention methods, including vacuum layers to prevent conduction and convection.
The page focuses on power measurements, efficiency calculations, and practical energy usage considerations.
Definition: Power is the amount of energy transferred per second by an appliance, measured in watts .
Vocabulary: Kilowatt-hour - The amount of energy transferred in 1 hour by a kilowatt-rated appliance.
Example: The efficiency formula: efficiency = × 100%
This section explains the particle theory and properties of different states of matter.
Definition: The particle model is a theory explaining the properties and behaviors of solids, liquids, and gases.
Highlight: Brownian motion demonstrates the constant movement of particles in liquids and gases.
Example: Materials expand when heated because particles vibrate more vigorously, taking up more space.
The final page covers density calculations and phase transitions between states of matter.
Definition: Density is the mass of a certain volume of material, calculated as mass divided by volume.
Vocabulary: Sublimation - The direct transition of a substance from solid to gas state.
Example: Evaporation can occur at any temperature at a liquid's surface, while boiling occurs throughout the liquid at its boiling point.
This page focuses on density calculations and the various processes of state changes in matter.
Definition: Density is the mass of a certain volume of material, calculated as mass divided by volume.
Vocabulary: State changes include melting, freezing, condensing, sublimation, and evaporation.
Example: Evaporation can occur at the surface of a liquid at any temperature, while boiling occurs within the liquid at a specific temperature point.
This page examines pressure in fluids and its relationship with temperature and volume.
Highlight: Pressure in fluids increases with temperature due to faster particle movement and more frequent collisions with container walls.
Example: In oceans, pressure increases with depth due to the increasing weight of water above, while on mountains, air pressure decreases with altitude due to less air above.
This page introduces the fundamental concepts of energy transfer and temperature relationships. The content explores how energy moves between objects and various transfer mechanisms.
Definition: Temperature is measured in degrees Celsius and represents the amount of energy stored in particles, measured in joules .
Highlight: Energy always transfers from hotter objects to cooler ones, following the fundamental laws of thermodynamics.
Example: During evaporation, the fastest-moving particles escape a liquid to form a gas, resulting in cooling of the remaining liquid.
Vocabulary: Radiation - A method of energy transfer through electromagnetic waves, particularly infrared radiation.

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
