States of Matter: Fundamentals of Phase Transitions

A deep understanding of matter's physical states is essential for success in chemistry, physics, and engineering. This course provides the foundational knowledge required to analyze how substances change phase and respond to environmental changes. By the end of this course, you will be able to confidently apply the gas laws, interpret phase diagrams, and explain the microscopic forces that dictate whether a substance is a solid, liquid, or gas. What you'll learn: * Understand the definitions and characteristics of solids, liquids, and gases based on kinetic molecular theory. * Apply the Ideal Gas Law and related empirical laws (Boyle's, Charles's, Avogadro's) to solve calculation problems. * Analyze the forces governing phase transitions, including vaporization, fusion, and sublimation. * Interpret complex phase diagrams, identifying triple points and critical points for pure substances. * Practice calculating deviations from ideal behavior using fundamental principles of real gas equations. The course begins with core terminology and definitions, progressing through detailed written explanations of gas laws and the energetics of phase changes. You will practice applying these concepts through targeted written exercises. This course is designed for absolute beginners with no prior knowledge of physical chemistry or thermodynamics. If you are starting your journey in physical science, this is the perfect starting point. Start building your essential scientific foundation today.
