It will sink in water and other light fluids but will float in (liquid) mercury or many other molten heavy metals.
Because a float switch is used to switch on or on an electrical current. The electricity needs to flow through good conductors like metals, and these metal parts are able to float in the mercury.
No, mercury is denser than ethanol, so it will sink and not float.
Mercury, although liquid, is denser than most solids - as a result, most solids will float on it. However, mercury may form alloys with many metals, and so your silver dollar may be damaged. It is also toxic.
no, mercury is a substanable resource meaning non waterised substance so cannot float in water No, mercury is heavier than water. It can't float in water. It is actually a metal that is liquid at room temperature and for several degrees around that. That's why it's used in thermometers.
Solid iron will float in liquid mercury. In most liquids it will sink.
No.
Yes, an object with a lower density than liquid mercury (13.6 g/cm³) would float on it. This is because objects float when they displace an amount of liquid with a weight equal to or greater than their own weight. Since the density of the object is lower than that of the liquid mercury, it will float.
Stones do not float in mercury because mercury is a very dense liquid, much denser than a stone. Any object denser than mercury will sink in it. In general, objects float in a liquid only if they are less dense than the liquid.
Water floats when it is turned into ice, because in this form it is less dense (it crystallizes, and the structure expands). It also can float in combinations of liquids, for example, it is less dense than liquid mercury, but more dense than oil, so it would 'float' on the mercury. Liquid mercury is very dense, and doesn't usually float on things.
Which rock? Any liquid that is dense enough will support a rock; the most common would likely be mercury, in which even iron floats.
No, wood would not float in mercury. Mercury is a dense liquid metal, much denser than water, so wood would sink in it.
Lead will sink in liquid mercury because lead is denser than mercury. Mercury is a heavy liquid metal, so most metals will sink when placed in it.
No, rocks are denser than mercury, so they would sink in mercury. Mercury is a very dense liquid at room temperature, so objects that are less dense than mercury will float on it.
No. Mercury is 12.5 times heavier than water. It goes straight to the bottom with no hesitation.
Mercury is the liquid that will settle at the bottom, as it is denser than both gasoline and turpentine. Gasoline and turpentine are less dense and will float on top of the mercury.
It will sink in water and other light fluids but will float in (liquid) mercury or many other molten heavy metals.
