Does Mercury float?
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.
Why does an egg sink in fresh water but float in salt water but stays in the middle when pour water into salt water?
Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.
How salty does the water have to be for an egg to float?
The water needs to be very salty for an egg to float. Typically, the water needs to have a salinity level of around 10-12% for an egg to float. This is much higher than the salinity of most oceans.
Ships float submarines sink?
Ships are designed with a hull that displaces enough water to keep them afloat, while submarines are designed to control their buoyancy and dive underwater by filling ballast tanks with water. This allows submarines to dynamically adjust their buoyancy and sink beneath the water's surface.
Does calcite float on water?
floating is a phenomena that is dependent of many factors including;density and base area.thus,looking at the density of calcite (approximately 2.7g/cc) it is greater than that of liquid water (1g/cc),hence calcite cannot float.nevertheless,in large body of water (sea,ocean) a block or pieces of calcite rock is bound to float due to surface area contrast.
