The Study of Chemistry
Many people, when they hear the word “chemistry,” think of scientists in white lab coats. They picture bubbling liquids, frothing (forming foam) and churning (stirring) inside mazes (picture, blend) of laboratory glassware. Is this a fair portrayal of chemistry and chemists? Certainly, chemistry happens in laboratories. Laboratory chemists often do wear white lab coats, and they do use lots of glassware! Chemistry also happens everywhere around you, however. It happens in your home, your school, your community, and the environment. Chemistry is happening right now, inside every cell in your body. You are alive because of chemical changes and processes.
Chemistry is the study of matter and its composition. Chemistry is also the study of what happens when matter interacts with other matter. When you mix ingredients (component) for a cake and put the batter (wet flour) in the oven, that is chemistry. When you pour soda water on a stain (dirt) to remove it from your favourite T-shirt, that is chemistry. When a scientist puts a chunk (piece) of an ice-like solid into a beaker, causing white mist (fog) to ooze over the rim (frame), that is chemistry, too.
bubbling liquid: chất lỏng sủi bọt (bong bóng nước)
frothing = forming foam: sự tạo thành bọt
churning = stirring: khuấy
maze = mixture = blend: hỗn hợp
portrayal = picture = description: miêu tả
ingredient = component: thành phần
batter = wet flour: bột ướt, bột nhão
pour: rót, đổ
stain = dirt: vết bẩn
chunk = piece: miếng, mẩu
mist = fog: sương mù
ooze: tan chảy
rim = frame: vành
