Page 2: Real vs. Ideal Gases and Charles' Law

This page explores the differences between real and ideal gases, and introduces Charles' Law gas volume temperature relationship.

Definition: Charles' Law states that at constant pressure, gas volume is directly proportional to absolute temperature.

Example: When a gas volume of 10.0 mL at 20.0°C changes to 30.0°C at constant pressure, the volume increases proportionally with temperature.

The page explains how real gases can be made to behave more like ideal gases by:

  • Increasing temperature
  • Decreasing pressure
  • Spreading particles further apart

Page 3: Boyle's Law and Gay-Lussac's Law

This page details how behavior of gases temperature pressure changes through two important gas laws.

Definition: Boyle's Law states that at constant temperature, pressure is inversely proportional to volume.

Definition: Gay-Lussac's Law states that at constant volume, pressure is directly proportional to absolute temperature.

Example: For Boyle's Law, when 10.0 mL of gas changes pressure from 1.50 atm to 2.00 atm at constant temperature, the volume decreases to 7.5 mL.

Page 4: Combined Gas Law

The final page introduces the Combined Gas Law, which integrates Charles' Law, Boyle's Law, and Gay-Lussac's Law into a single equation.

Highlight: The Combined Gas Law allows calculations involving simultaneous changes in pressure, volume, and temperature.

Example: The page includes a problem solving example involving gas volume changes under different pressure and temperature conditions at STP (Standard Temperature and Pressure).

Combined Gas Laws

This page covers the integration of individual gas laws into the combined gas law equation.

Definition: The combined gas law unifies Charles', Boyle's, and Gay-Lussac's laws into a single equation: P₁V₁/T₁ = P₂V₂/T₂.

Example: A detailed problem shows how to calculate new gas volume under changing temperature and pressure conditions.

Graham's Law of Diffusion is also introduced, explaining how gas diffusion rates relate to molecular mass.

Page 1: Kinetic Molecular Theory Fundamentals

The first page introduces the fundamental principles of Kinetic Molecular Theory real gases differences. The theory consists of nine key principles that explain gas behavior at the molecular level.

Definition: Kinetic Molecular Theory (KMT) is a scientific model that explains the behavior of gases at the molecular level.

Highlight: Gas particles move in random motion and undergo completely elastic collisions, maintaining constant total kinetic energy at a given temperature.

Key principles include:

  • Gases consist of tiny particles atoms/moleculesatoms/molecules
  • Particles are widely separated with significant empty space
  • Particles move in straight-line random motion
  • Collisions between particles are elastic
  • Particle speeds vary based on mass but maintain constant average speed at specific temperatures

Vocabulary: Elastic collisions - collisions where total kinetic energy remains constant.

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.

Samantha Klich

Android user

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.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

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.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
