The liquid with a lower density float over the liquid with a highrer density.
When most liquids change to their solid state, they become denser. However, water freezes and the resulting solid, ice, is less dense than it's liquid state (aka ice floats over liquid water)
Any material that has less density than the liquid on which it is supposed to float.
gasoline/petrol,,,,,,,,,,, oil base products
A class B or "Bravo" fire is any fire involving the combustion of liquids such as gasoline, diesel, liquid paint, solvents, or oils. These can usually be extinguished using some form of vapor seal over the liquid like aqueous film forming foam (AFFF, essentially REALLY soapy water that floats over any other liquid). Other extinguishing methods are smothering, and dry chemical extinguishing agents like PKP or Sodium Bicarbonate. Water is typically a bad choice of extinguishing agent for this type of fire since you may end up actually spreading it and making the fire worse.
Which rock? Any liquid that is dense enough will support a rock; the most common would likely be mercury, in which even iron floats.
Water and basically any other liquid.
Well, trees for one, bamboo, and any other plant that floats.
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.
Of course. Fresh water floats on salt water, warmer water floats on cooler water, and ice floats on any water.
Any item that floats displaces an amount of water equal to its own weight. This is known as Archimedes' principle.
The tanker is loaded with lpg or any other liquid . By pushing the liquid with high pressure pneumatic nitogen or any other inert gases.Inert gas will be pushed through the vapor line and liquid starts to comeout from liquid line to other empty source.
because egg contains air cavity in it ..
