Why does oil float on water? Why is ice floating on water beneficial to the biosphere? Why do denser objects sink? Why did the Antarctic Ice Shelf crack? Why does the human body float in water? Please explain thoroughly why ice is less denser than liquid water. ...
Or think of crude oil that spills from a tanker in the ocean and floats on top of the water. There are two main reasons why don’t oil and water mix even if they are put in the same container. Both these reasons consider these two substances on a very small scale. Everything around...
Describe why ice floats on water. Why does I_2 have a higher boiling point than F_2? Explain briefly why CuSO4 dissolves more easily in water than an organic solvent. Why is NaCl described as a strong electrolyte? "Hard water" contains relatively high concentrations of C a 2 + . Explain...
Oil floats over water and thus oil fires cannot be extinguished using water. Water flows on and it has the risk of spreading the fire along. In case of electric fires water cannot be used as an extinguisher. It being a good conductor of electricity, puts the life of the man spraying it...
What property makes ice float on water? Ice floats on top of water because it has a lower density. Density is a substance's mass per unit volume. Because ice crystals take up more space than liquid water, they have a higher volume and a lower density.Why...
Ice and Water– Show kids that ice floats. But wait….ice is water? Put water in a paper cup and make a line on the side to show the level of water. Now put the cup in the freezer until freezes. The water expands as it freezes. Now even though the mass (weight) is the same,...
1. On the “soup surface very quick forms thick lubricant film”: Is because the oil density is smaller than the soup density, the oil floats on the soup surface forms the lubricant film.[translate] athese days.[translate] a我想你可以给我一次机会 正在翻译,请等待... ...
When particles are placed in water, one of three things can happen: Theydon’t mix(e.g., oil floats to the top, sand sinks to the bottom). Theydissolve(e.g., salt). They form acolloidal suspension(e.g., milk) in which each particle isrepelledfrom the other and evenly distributed...
As ice is less dense than water, it floats. It is found that ice occupies 9 percent more volume than water and hence it weighs lesser than water. As ice displaces the heavy weight water, it floats on the top of water. This is the reason why at the places like rivers and lakes seve...
aThe white swan-with its long,graceful neck-is among the most beautiful birds.The swan is mostly silent throughout ist life.It floats quietly on the water,unable to sing sweet songs.[translate] aIn the center of the school there is a new teaching building, which is very clean and beautifu...
