Chemistry not only helps us make products for use,but it also helps us understand the world around us.Chemistry helps us understand what the ozone layer is and how it protects us.Chemistry also gives us sunscreen to protect us from the sun.Thanks to chemistry,we know bleach can't be mixed with vinegar,because it can produce poisonous gas.Without chemistry,we wouldn't have fireworks displays on important days.Chemistry plays a big role in food preparation.Cooking food causes it to go through a chemical change.That is why cooked food often tastes different from raw food.Baking is a great example of chemistry.Too much or too little of any ingredient makes a difference to the result of baking,for example,the dough won't rise or the cake will be flat.Chemistry isn't something that just lives in a lab;it's something that you meet hundreds of times every day.Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest-looking things.
化学不仅帮助我们制造可以使用的产品,也帮助我们去了解认知周围的世界.化学帮助我们去了解什么是臭氧层,它是怎样保护我们.化学也可以做成防暑产品保护我们不被晒伤.我们知道了漂白剂不能与醋混合,因为这会产生有毒气体.没有化学,在重要的日子我们就没有烟花爆竹可以使用.化学在食物准备方面有很重要的作用.实际上炒菜就是一个化学反应的过程.这就是为什么炒过以后的菜与生的时候味道是不同的.烘焙也是一个很明显的化学反应的例子.太多或者太少的调料都会使烘焙的结果不同.比如生面团如果不发酵,蛋糕就是平的.化学不是只在实验室才有的,而是你每天会遇到数百次的东西.知道化学是如何作用以后,你就会对非常简单的事物背后的科学知识有一个更好的理解
