Systems and Energy

This section discusses different types of systems in thermochemistry and introduces the concept of internal energy.

Definition: A system is the area of focus in a chemical reaction, while the surroundings are everything else.

The page explains three types of systems: open, closed, and isolated. It also introduces internal energy EE as the sum of kinetic and potential energy of particles in a system.

Vocabulary: Internal energy includes kinetic energy from molecular motion translational,rotational,andvibrationaltranslational, rotational, and vibrational and potential energy from bonds and intermolecular forces.

The page concludes with formulas for calculating changes in temperature and energy, introducing the concepts of heat qq and work WW.

Enthalpy and Energy Changes

This page focuses on enthalpy and various types of energy changes in chemical reactions.

Definition: Enthalpy HH is the total energy of a system at constant pressure. It is an extensive property measured in kJ/mol.

The section covers different types of enthalpy changes, including enthalpy of reaction, combustion, solution, fusion, and vaporization.

Example: For a chemical reaction, ΔHreaction = ΔH products - ΔH reactants. If ΔHrxn is positive, the reaction is endothermic; if negative, it's exothermic.

The page also includes enthalpy diagrams and potential energy diagrams to visually represent endothermic and exothermic reactions.

Heat Capacity and Calorimetry

This section introduces heat capacity, specific heat, and calorimetry techniques.

Definition: Heat capacity CC is the quantity of heat required to change the temperature by 1°C or 1K. Specific heat CpCp is the heat capacity per unit mass.

The page provides formulas for calculating heat capacity and specific heat, including the useful equation q = mcΔT.

Vocabulary: Calorimetry is the measurement of heat flow using an instrument called a calorimeter.

The section explains thermal equilibrium and describes coffee cup calorimetry, a common technique for measuring heat changes in reactions.

Thermochemical Equations and Problem Solving

This page focuses on thermochemical equations and problem-solving techniques in thermochemistry.

Definition: Thermochemical equations describe the reaction and energy changes during a chemical process, with ΔH written in the products or to the side.

The section explains how to manipulate thermochemical equations by flipping the equation or multiplying it by a factor, emphasizing that the ΔH must also change accordingly.

Example: A problem-solving example is provided, calculating the heat involved in the dissolution of KCl in water using calorimetry data.

The page concludes with information on using ΔH as a conversion factor in thermochemical calculations.

Thermochemistry Fundamentals

This page introduces key concepts in thermochemistry, including heat, temperature, and energy. It explains the first law of thermodynamics and different forms of energy.

Definition: Thermochemistry is the study of heat changes in chemical reactions and state changes.

Vocabulary: Heat is a form of energy that flows from warm to cool objects. Temperature measures the average kinetic energy of particles.

The page covers various energy units, including joules, calories, and British Thermal Units. It also introduces the first law of thermodynamics, also known as the law of conservation of energy.

Highlight: The first law of thermodynamics states that energy cannot be created nor destroyed.

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.

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!

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
