According to the College Board, "Transformations of matter can be observed in ways that are generally categorized as either a chemical or physical change. The shapes of the particles involved and the space between them are key factors in determining the nature of physical changes.
The properties of solids, liquids, and gases reflect the relative orderliness of the arrangement of particles in those states📚, their relative freedom of motion🏃, and the nature and strength of the interactions between them💪. There is a relationship between the macroscopic properties of solids, liquids, and gases, as well as the structure of the constituent particles of those materials on the molecular and atomic scale. In subsequent units, students will explore chemical transformations of matter."
How do interactions between particles influence mixtures?
Why does the smell of perfume💐 only last a short time?
Why can you swim in water🌊 but you cannot walk through a wall🧱?
How are the properties of gases described?
How can you determine the structure and concentration of a chemical species in a mixture?
Welcome to unit 3 of AP Chemistry! This unit is titled "Intermolecular Forces and Properties". In previous units, we've learned all about intramolecular forces, things like how atoms are built, orbitals, bonding, etc.
In this unit, we dive deep into what happens when you put a bunch of molecules (or atoms, but mostly molecules) together. We begin with a look at intermolecular forces and the states of matter, then move into gases and solutions. This unit is super exciting😆 because there are tons of real-world, out of lab experiences you have with these concepts EVERY DAY😲 and we'll come to learn all about them.
About 18-22% of the exam is about this unit! It's the largest unit on the exam but really interesting, so let's get to it🧠!
