What do you understand about ''Chemistry'' ?

Do you know, we use  various chemicals in our daily life? For examples, vinegar is an acidic chemical, soap is a basic chemical and distilled water is a neutral chemical. Even, burning paper, lighted gas and rice being cooked are among the chemical changes which occur around us. I like chemistry because understanding chemistry helps me to understand the world around me. Cooking is chemistry. Everything I can touch or taste or smell is a chemical. When you study chemistry, you come to understand a bit about how things work. Chemistry isn't secret knowledge, useless to anyone but a scientist. It's the explanation for everyday things, like why laundry detergent works better in hot water or how baking soda works . If you know some chemistry, you can make educated choices about everyday products that you use.
