A. Pressure
B. Density
C. Both A & B
D. Velocity
🧠 Explanation:
Ice floats on water because its density is lower, about 0.92 g/cm³ compared to water’s 1 g/cm³. When water freezes, its molecular structure forms a less compact lattice, causing it to expand. This property is key in physics and environmental science, affecting aquatic ecosystems by insulating water below ice. Understanding ice’s buoyancy explains natural phenomena like lake freezing, vital for studying climate and ecological systems, with applications in hydrology and environmental management for sustainable water resources.
