Final answer:
Clear ice is a transparent and impurity-free type of ice that forms when water freezes slowly. It is commonly used in cocktails and sculptures.
Step-by-step explanation:
Clear ice is a type of ice that is transparent and free from impurities or air bubbles. It is formed when water freezes slowly and the impurities and air bubbles have time to escape, resulting in a solid ice block with a clear appearance. Clear ice is often used in cocktails and sculptures due to its aesthetic appeal.
Properties of Clear Ice
Transparency - Clear ice is transparent because of slow freezing and the exclusion of air and impurities.
Low Impurities - The slow freezing process allows impurities and gases to be displaced from the ice, resulting in high clarity.
Crystal Lattice Structure - Clear ice has a uniform and extended crystal lattice due to the orderly arrangement of water molecules.
