This is important because this property preserves marine life by not letting the temperature of water change rapidly. - Ice is lighter than liquid water.What Is Water Made Up of? Water makes up around 60% of the human body. It also covers 71% of the earth's surface. Wate...
1.The paper studied the change of straw decomposition, soil physical and chemical property, soil nutrient and crop yields under straw mulching.通过在川中丘陵区简阳市进行的秸秆覆盖还田试验,研究了秸秆还田后秸秆腐解过程及养分释放规律和对土壤理化性质和作物产量的影响,结果表明: (1)秸秆含有丰富的养分,秸...
It also has the property, when it is dissolved in water,of produ- cing a white precipitate when a solution of silver nitrate is added to it,and it has many other chemical properties. Iron has the property of combining readily with the oxygen in moist air to form iron rust; whereas an ...
