此外,喷出水体中的小型活体动物很可能被热冲击和/或化学冲击杀死或击昏,从而增加了喷口的食物供应。
In addition, it is likely that small live animals in the advected water might be killed or stunned by thermal and/or chemical shock, thereby contributing to the food supply of vents.
正如我们所说,这些热液喷口正在向海洋深处释放这种强热的水,含有一种叫做硫化氢的化学物质,和一种气体,二氧化碳。
As we said, these hydrothermal vents are releasing into the ocean depth this intensely hot water that contains a chemical called hydrogen sulfide, and also a gas, carbon dioxide.
可以考虑化学热包来温暖你的手脚。
Consider using chemical heat packs to warm up your hands or feet.
Then we went on to look at thermochemistry, and that's what I want to continue today.
然后我们继续研究了热化学,这是我今天要继续讲的,的确。
Right? In other words I've got the stoichiometric coefficients in there and the values, and I'm subtracting the reactants from products -1652kJ/mol wind up with minus 1652 kilojoules per mole.
对吧?换句话说这里我用了化学,计量系数和生成热的值,从生成物中减去反应物,最后得到。
See you Friday. We'll finish on calorimetry and thermochemistry and then we'll start in on one of the really most difficult topics that we'll deal with all semester, which is a second law and our special function that
好,我们周五见,我们会讲完量热法,和热化学的内容,然后我们会开始,讲这个学期最难的话题之一,第二定律以及我们
