Ice

Ice is the solid form of water that forms when water freezes at a temperature of 0 degrees Celsius (32 degrees Fahrenheit). It is found in glaciers, icebergs, and frozen bodies of water such as lakes and rivers. Ice is also commonly used for cooling drinks and preserving food.

Properties of Ice

• Physical State: Ice is a solid at temperatures below 0 degrees Celsius.
• Crystal Structure: Ice has a hexagonal crystal structure, which gives it its unique pattern of six-sided shapes.
• Density: Ice is less dense than liquid water, which is why it floats on water.
• Transparency: Ice is transparent, allowing light to pass through it.

Formation of Ice

Ice forms when water molecules slow down and come together to form a crystalline structure. This occurs when the temperature drops below the freezing point of water, causing the molecules to arrange themselves into a solid lattice.

Uses of Ice

Ice has many practical uses, including:

• Preserving and storing food
• Cooling drinks
• Creating artificial skating rinks
• Ice sculpting and carving
• Scientific research and experiments
