Answer 2

• Cooking entails a chemical change in the food's composition, hence it is a chemical change.
• The raw elements of the veggies can no longer be recovered after they have been cooked.
• Chemical synthesis or, alternatively, chemical breakdown into two or more separate chemicals occurs when one component interacts with another to generate a new material.
• Chemical reactions are the name for these processes, and they are not reversible in most cases until they are followed by other chemical reactions.
• Exothermic processes generate heat, while endothermic reactions require heat to occur.
• Chemistry is a science that revolves around understanding chemical changes.
