A mixture is a substance comprising two or more components that are not chemically bonded. Ice is the solid state of water (H₂O). Water is a chemical compound, meaning it is formed from different elements (Hydrogen and Oxygen) chemically combined in a fixed ratio. A compound is considered a pure substance. Ice-cream is a mixture of water, milk solids, sugars, fats, flavorings, and air. Air is a mixture of gases, primarily nitrogen, oxygen, argon, and carbon dioxide. Honey is a mixture consisting mainly of sugars and water, along with other components like enzymes, minerals, etc.

- Which of the following is/are the example/ examples of chemical change? 1. Crystallization of sodium chloride 2. Melting of ice 3. Souring of milk Select the correct answer using the code given below.
- Crystallization of sodium chloride: This is a process where dissolved salt precipitates out of a solution as crystals. It is a physical change because the chemical composition (NaCl) remains the same. 2. Melting of ice: This is a change of state from solid water (ice) to liquid water. It is a physical change because the substance is still water (H₂O), just in a different form. 3. Souring of milk: This occurs when bacteria convert lactose (milk sugar) into lactic acid. This process creates new chemical substances (lactic acid) and changes the milk's properties (taste, smell, texture). This is a chemical change. 140.
