Study Notes
Chemical Reactions
- When an iron tawa/pan/nail is left exposed to humid atmosphere, it undergoes rusting, a type of oxidation reaction where iron reacts with oxygen in the air to form iron oxide.
Food and Temperature
- When milk is left at room temperature during summers, it undergoes bacterial fermentation, leading to curdling and spoilage due to the growth of microbes.
Fermentation
- When grapes get fermented, yeast consumes the sugars present in the grapes, producing ethanol and carbon dioxide as byproducts, resulting in the production of wine.
Cooking and Chemical Reactions
- When food is cooked, various chemical reactions occur, such as Maillard reaction, caramelization, and denaturation of proteins, which alter the texture, flavor, and nutritional content of the food.
Respiration
- When we respire, cellular respiration occurs, where glucose is broken down to produce energy in the form of ATP, releasing carbon dioxide and water as byproducts.
