Crude oil processing and fractional distillation are key processes in... Show more
This section details the process of fractional distillation and its various products. The process begins with heating crude oil into a gas and separating it in a fractionating column.
Definition: Fractional distillation is a separation technique based on different boiling points of substances.
Highlight: The fractionating column is hottest at the bottom and coolest at the top, allowing different hydrocarbons to condense at different heights.
Example: Bitumen, used for road surfacing, condenses at the bottom, while lighter fuels like butane and propane rise to the top.
This page explores crude oil's composition and separation methods. It details how different hydrocarbon sizes affect various properties.
Definition: Crude oil is a mixture of hydrocarbons that has formed in underground reservoirs over millions of years.
Highlight: Small hydrocarbons have lower boiling points, are more flammable, and produce cleaner flames compared to larger hydrocarbons.
Example: The separation process involves heating the mixture into a gas and allowing it to condense at different heights in the fractionating column.
The final page examines specific hydrocarbon examples and their properties, focusing on decane and pentane.
Definition: Hydrocarbons are compounds made up of only carbon and hydrogen atoms.
Example: Decane has a higher boiling point than pentane and produces a 'dirtier' flame.
Highlight: Kerosene typically contains hydrocarbons with 10-16 carbon atoms per molecule and is a mixture, not a pure substance.
Vocabulary: Fractions are mixtures of hydrocarbons with similar boiling points, allowing for some variation in molecular size.
This page introduces fundamental concepts about alkanes and their properties. The text explains how different alkanes are structured and their characteristics.
Definition: Alkanes are hydrocarbon compounds containing only single bonds between carbon atoms.
Example: Methane is the smallest alkane, followed by ethane, propane, and butane in increasing size.
Highlight: Butane has a higher melting and boiling point than propane due to stronger intermolecular forces.
Vocabulary: Van der Waals forces are the weakest type of intermolecular forces, while hydrogen bonds are the strongest.

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!

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
