No.
Oil is denser than cork, so the cork would float.
That depends on the relative densities of the solid and the liquid. If the solid is denser than the liquid, the solid will sink. If the liquid is denser, the solid will float.
A hydrometer consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. Mercury has a higher density, thus a lower volume for the same weight than lead. It is a toxic liquid metal, but also more dangerous and difficult to clear up the mess when a glass hydrometer is broken
The liquid metal in many thermometer is mercury (Hg).
Barometers can use any liquid. A dense liquid that makes for a short column at room temperature, is mercury.
Yes, nickel can float on liquid mercury because the density of nickel is lower than that of mercury. This means that nickel will not sink when placed on liquid mercury, and instead will float on its surface.
Solid iron will float in liquid mercury. In most liquids it will sink.
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.
Yes, liquid mercury does float in water because it is denser than water. This means that the weight of the mercury displaces an equal weight of water, causing it to float on the surface.
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, but it will float in mercury. Depends on what the liquid is.
