我喝可乐等碳酸饮料时,看见饮料瓶总是鼓鼓的。打开瓶盖,有时会有一股气流“噗”的一下冲出来。我纳闷地问爸爸,这股气流是从哪里来的?爸爸说,从瓶中冒出来的气体是二氧化碳气体。在碳酸饮料的生产过程中,生产厂家采取增大压力的办法,将二氧化碳大量溶于水中。如果压力减小,二氧化碳就会从水中跑 When I drink Coke and other carbonated drinks, I saw that the beverage bottle always darkened. Open the cap, and sometimes there will be a stream of air, “pop” look rushed out. I wonder to ask my father, where is the flow of air? Papa said the gas coming out of the bottle is carbon dioxide gas. In the production of carbonated drinks, manufacturers take the approach of increasing pressure, a large number of carbon dioxide dissolved in water. If the pressure is reduced, carbon dioxide will run from the water
