Introduction to Physical Science: Matter in Our Surroundings

Everything around us, from the air we breathe to the water we drink, is made of matter. Understanding its physical nature and behavior is the first step toward mastering chemistry and physics. This course guides you through the foundational concepts of matter, explaining how particles interact, change states, and respond to temperature and pressure. You will build a strong scientific vocabulary and a clear mental model of the physical world. What you'll learn: - Understand the particulate nature of matter and how particles behave. - Classify the states of matter, including solids, liquids, gases, and modern concepts like plasma. - Explain phase transitions such as melting, vaporization, sublimation, and condensation. - Analyze the effects of temperature and pressure changes on different substances. - Define evaporation and identify the key factors that influence its rate. - Apply standard SI units for temperature, volume, mass, and pressure. The course begins with core definitions and the physical characteristics of particles, then progresses to state changes, thermal energy, and real-world applications of evaporation. This course is designed for absolute beginners, students starting their chemistry journey, or anyone looking to refresh their basic scientific knowledge with no prior prerequisites required.
