no longer dissolve sugar, it becomes a“saturated(饱和的)solution" This means that sugar starts forming at the bottom of the glass.The reason why the hot water dissolves more is that it has faster moving molecules(分子) which are spread further apart than the molecules in the cold water. ...
The most efficient water (Other than solar) is an electric hot water heater. Both an electric tank hot water heater and an electric tankless hot water heater are 100% efficient. There is no flue for hot gases to escape so all of the energy consumed in used to heat water. Nothing is wa...
根据最后一段“The reason why the hot water dissolves more is that it has faster moving molecules (分子) which are spread further apart than the molecules in the cold water. With bigger gaps between the molecules in the hot water, more sugar molecules can fit in between them. (热水溶解更多...

Although the lashing was at first lethargic, it quickly worked up to a faster tempo. More and more of the sea, up to a quarter of a mile out, became covered with the flailing seaweed that punished and struck at the water repeatedly in idiot hatred of all life but its own. Directly ...

通读文章,结合最后一段关键句 “The reason whythe hot water dissolves more is that it has faster moving molecules(分子) which are spread further apart than the molecules in the cold water.” (热水溶解更多的 原因是它有比冷水中的分子扩散得更远的、运动更快的分子。)可知,文章主要介绍了一个实验...
It has been found that the use of starch, instead of more water soluble powders, surprisingly provides for faster dispersion of the component of interest when the desired liquid (e.g., milk or water) is added to the food product. Dispersion of the component of interest, then, provides the...
Running the jets in your hot tub will help cool it faster — a trick that works particularly well in the evening. The jets will also help circulate any cold water that you've added to the tub. Jets lower the water temperature by injecting cool air into it. The same thing happens when...
The reason why the hot water dissolves more is that it has faster moving molecules(分子)which are spread further apart than the molecules in the cold water.With bigger gaps between the molecules in the hot water,more sugar molecules can fit in between them.(1)What isn't needed in the ...
