More than 100 new videos covering everything from photoelectron spectroscopy to intermolecular forces.Every question includes hints or rationales to help students improve their understanding. Over 640 AP -style questions tightly aligned to topics on the exam.In its current form, AP Chemistry beta covers topics from the first seven units of AP Chemistry. Eventually, the beta course will replace the older AP Chemistry course that is already on Khan Academy.
What do we mean by “beta” in this context? In short, this course is work in progress: not only will we be adding more content over time, but we’ll also be making changes to already-released content based on feedback from users like you. So, check out this course and learn more about the behavior of gases, today.Khan Academy is excited to announce the launch of a brand-new science course: AP® Chemistry beta! Because they are a simplified model of real gas, they can help explain the basics of the kinetic molecular theory which states that an increase in temperature raises the average kinetic energy of the molecules. Studying the concept behind an ideal gas equation, PV=nRT, can help you describe the relationship between pressure, volume, amount, and temperature of a gas. Plus, you will study the core units of measure for temperature.
This course will also teach you how changes to pressure, temperature, or volume affect each other. You will study the Ideal Gas Law with the famous equation PV=nRT, its characteristics, and how to solve for any part of this general gas equation. This course will teach you how to calculate the pressure of a gas-filled container. You will learn that gas molecules exert no attractive or repulsive forces on each other which make their collisions elastic. This course will introduce you to an ideal gas, which is a theoretical gas. A gas mixture, such as the air we breathe, contains different types of pure gases. A pure gas may be composed of individual atoms, elemental molecules made from one type of atom, or compound molecules made from different atoms. Gas is one of the four fundamental states of matter (solid, liquid, gas and plasma).
