Ice floats in water because, unlike most substances, the solid phase of water is less dense than its liquid phase. When water freezes, it expands slightly, and the resulting change in density is enough to allow ice cubes to float in a glass of water.Continue Reading
Ice's expansion at its freezing point is due to the polar structure of water molecules. In the liquid phase, water molecules are always in motion and can be packed closely together. As the temperature drops, however, the molecules begin to form hexagonal crystals. The hydrogen bonds created in these crystals arrange the molecules in such a way that more space exists between them than in the liquid phase, resulting in an expansion of around 8.3 percent in volume. Since the water the ice displaces now weighs less than the ice itself, ice is buoyant and floats.
This unique property is important to the development of life on earth. Because ice floats, rivers and streams form a layer of ice during winter. If water behaved like most other solids and became denser when cooled, this ice would fall to the bottom of each body of water, freezing it solid and killing any living things under the surface.Learn more about Thermodynamics
Ice cubes float in water because ice has a lower density than water. This lower density means that ice weighs less than water in its liquid form.Full Answer >
For a total of four servings, use 6 ounces of orange juice, 1 cup of milk, one cup of water, 1/4 cup sugar, 1 teaspoon of vanilla extract and eight to twelve individual ice cubes. Combine elements in a blender, blend together until smooth, pour in glasses and serve.Full Answer >
The primary difference between a frappé and a milkshake is the recipe used for each; a basic frappé is made with water, sugar, instant coffee and ice cubes, while a basic milkshake consists of blended milk and ice cream. The two drinks are often confused because of their similar textures.Full Answer >
The energy required to change the temperature of a substance with no phase change is known as sensible heat. The change in temperature may come from the sun via the soil or the air.Full Answer >
