Why does ice float on water? A. Ice is lighter than water B. Ice is colder than water C. Ice is harder than water D. Ice is smoother than water 相关知识点: 试题来源: 解析 A。解析:冰的密度比水小,所以冰能浮在水面上。冰的温度、硬度、光滑程度都不是其能浮在水面上的原因。
an object placed in a fluid experiences an upward force, known as the buoyant force, equal to the weight of the fluid displaced by the object. In the case of ice floating on water, the weight of the water displaced by the ice is equal to or...

The singular rule of thumb, when it comes to the ability of an object to float in water (or any other liquid), concerns the density of the object in question. Have you ever heard of Archimedes’ Principle? Archimedes’ Principlestates that for an object to float on water, it must displa...

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...
According to the Archimedes Principle, an object will float in a fluid if it is less dense than the fluid. Ice is less dense than water. The lighter ice displaces a volume of water equal to its own weight. The buoyant force from that displaced water keeps the ice afloat on top of liq...
Why does hydrogen bonding help ice cubes float? What is the reason for ice being less dense than water? Why does ice stay at the top of oceans instead of sinking to the bottom? Why does oil float on water? Why is ice floating on water beneficial to the biosphere?
