Explain why ice floats.
Understand the Problem
The question is asking for an explanation of the principle that causes ice to float on water. This involves concepts related to density and the structure of water molecules as they freeze.
Answer
Ice floats because it is less dense than water.
Ice floats on water because it is less dense than liquid water. When water freezes, its molecules form a stable structure with hydrogen bonds, increasing its volume and decreasing its density.
Answer for screen readers
Ice floats on water because it is less dense than liquid water. When water freezes, its molecules form a stable structure with hydrogen bonds, increasing its volume and decreasing its density.
More Information
This phenomenon is crucial for aquatic life; it insulates the water below, keeping it from freezing solid and providing a stable environment for marine organisms.
Tips
A common mistake is not connecting the concept of density to molecular structure. Ensure you understand that hydrogen bonds in ice cause the structure to expand, lowering its density.
