Lesson 003-A: Water – The Exception! | Why Ice Floats, Expands & Even Sublimes

Why is water so different from almost every other substance? In this lesson of Zig's Chemistry 42, we explore the remarkable properties of water and discover why it plays such an essential role in nature and life. In this video you will learn: Why the phase diagram of water is unique Why ice melts under pressure Why pressure melting alone does not explain ice skating How glaciers slowly move Why ice floats on water Why water expands when it freezes Why frozen cells are damaged What sublimation is Why frozen laundry dries outdoors How freeze-drying is used in the food and pharmaceutical industries Water may look simple, but it behaves in extraordinary ways. Understanding these properties helps us explain many everyday phenomena—from bursting water pipes to preserving food and medicines.
