今天,天气十分炎热。上课时,郭老师带来了一瓶可乐要和我们分享我们高兴极了.
Today, it's very hot. In class, Mr. Guo brought a bottle of coke to share with us
郭老师看了看可乐瓶,发现可乐太少了,不够我们喝,于是我们一起想办法,想了很久都没想出来。忽然,郭老师不小心摇了一下可乐,冒出了气泡而且涨了一点。我们惊奇地问到:“这是为什么呢?”“对呀!这是怎么回事呢?”郭老师也忙问到。有的同学说:“是泡泡。”有的说:“不对。是可乐。”“……”同学们七最八舌的议论着。这时,郭老师说话了:“这是工人叔叔再制造可乐时往里面强压进了二氧化碳,一摇,二氧化碳就和一些可乐就变成气泡了。我使劲的摇,可乐瓶里气泡就会越来越多,会充满整个瓶子。”听到这儿,同学们都恍然大悟的笑了。这时郭老师边打开瓶盖边说:“现在我们开始喝可乐了!”话刚说完,可乐“丝、丝、丝”的一声“冲”了出来打湿了郭老师的衣服和手。同学们都惊叫了起来:“哇……怎么可乐会向外冲呢?”“这还是二氧化碳……等会你们喝下去可乐时呼出来的也是二氧化碳。”郭老师慢声慢气的向我们解释着。
Mr. Guo looked at the coke bottle and found that there was too little coke for us to drink. So we worked together and didn't come up with a solution for a long time. All of a sudden, Miss Guo accidentally shakes the coke and bubbles up a little. "Why?" we asked in surprise "Yes! What's going on? " Teacher Guo asked. Some students said, "it's bubbles." Some said, "No. It's coke. " "..." The students talked about it seven times. At this time, Mr. Guo said: "this is the worker's uncle forced carbon dioxide into the coke when he made it again. When he shook it, the carbon dioxide and some coke would become bubbles. I shake it hard, there will be more and more bubbles in the coke bottle, and it will fill the whole bottle. " Hearing this, the students all laughed suddenly. At this time, Mr. Guo opened the bottle cap and said, "now we start drinking coke!" Just finished, coke "silk, silk, silk" a "rush" out to wet Miss Guo's clothes and hands. The students all exclaimed: "wow How can coke rush out? " "It's still carbon dioxide When you drink coke later, you will also breathe out carbon dioxide. " Teacher Guo explained to us in a slow voice.
