What type of change has taken place when you start out with water and a glass and you freeze it is that a physical change or a chemical change also and 2 to 3 sentences in your own words describe why you chose that type of change in the previous question Key points that you can include in your answer are the definition of physical or chemical change the start in products and a physical or chemical change and the start and appearance in a physical chemical change and last, but not least particular evidence observed to indicate a physical or chemical change

Answer 1

The process of freezing water into ice is a physical change. This is because the chemical structure of water (H₂O) remains the same; it simply changes from a liquid state to a solid state. The appearance changes from liquid water to solid ice, but no new substances are formed, and the change is reversible—melting the ice will return it to water. The key evidence indicating a physical change is the change in state and temperature without altering the chemical composition.
