Why do things float in water is really a great question. In order to understand the concept, you will need to review the lesson about density, Archimedes' principle and buoyancy.Whether an object floats or sinks
Why might an egg float in saltwater but sink in fresh water?
Explain the concept of buoyancy and why some objects float while others sink.相关知识点: 试题来源: 解析浮力是流体对浸入其中的物体施加的竖直向上的力,其大小等于物体排开流体的重量。物体浮沉取决于其密度与流体密度的关系:密度小于流体时上浮,反之则下沉。
The positioning of molecules affects the density of an object. Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense ...
(Density of water =1000kg/m3) View Solution Why do bodies become weightless in artificial satellites ? View Solution Take a small cotton ball and place it in a tumbler/bowl filled with water. Observe it for atleast 10 minutes. Will it float or sink in water and why? View Solution ...
Does Your Poop Sink or Float? (And Why It Matters) While the subject of our bathroom habits is usually either brushed under the rug or discussed in the form of embarrassing jokes, it is actually a complex and importantarea of healththat should not be ignored....
Does cork sink or float in seawater? The cork weighs less than both the fresh water and salt water, which is whyit will float in both solutions. ... The tendency of an object to float in a liquid is called buoyancy, and the cork is more buoyant in the salt water. ...

Generally, a healthy stool sample tends to sink straight to the bottom of the bowl. This tendency comes down to one simple fact: density. Stool as a substance is denser than water, which causes it to sink into the water. Why Then, Does Some Poop Float?
Why is water more dense than ice? Why does air sink at the poles? The air pressure in the tires of a car increases during driving. Explain. Why do stars fall? With an airplane wing, how does the air above the wing move faster and therefore provide less pressure, and why does this ...
