It depends entirely on the amount of salt in the water. Pure water has a density of 1 kg/L. Any item that is less dense than 1 kgL, will float. Items with a greater density will sink. As you increase the salinity of water, the density of the salt adds to the water's density. The Dead Sea, for example, has a high saline level (31%) and it's density is 1.24kg/L. An average sized person can easily float in these waters.

Huh, can't you float a thumbtack in water? If it sinks, it means that the amount of water displaced weighs less than the tack.
An egg is one such thing.
A boiled egg will typically sink in fresh water because it is denser than the water. However, if the egg is older and has developed an air pocket inside, it may float. Fresh boiled eggs are less likely to float compared to older ones due to their lower air content.
Objects float or sink because of their density. An example of an object with low density is a sponge, as it has loads of air bubbles in it, and will float. An example of an object with high density is a brick. This is because the brick doesn't have any air trapped in it, it is "packed in", and is more dense than water, therefore it will sink.
An egg that sinks in water is fresh, while an egg that floats is not fresh.
aboat floats because it displaces it,s weight in water when that happens it stops sinking a penny cannot displace it,s weight in water so it sinks hope you understand
No, Fimo does not float in water. It is a type of polymer clay that is dense and sinks in water.
Fresh eggs float in salt water because the density of salt water is more than the density of the egg. But fresh eggs do not float in fresh water because the density of water is less than that of the egg. Salt increases the density of water.
No, it sinks.
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
Though each egg contains a small air space, it is not usually big enough to act like a float, so the egg sinks. A bad egg will produce gases as the egg decomposes inside the shell. As these gases take on a larger volume, so the egg will float.
The older an egg is the more likely it is to float. If it actually sits on the surface it may actually have gone bad.
The difference in density between the perspex block and the water is what determines whether it sinks or floats. In fresh water, the density of the perspex block is greater than that of the water, causing it to sink. However, in very salty water, the increased density of the water allows the less dense perspex block to float.
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
No, it sinks.
A perspex block sinks in fresh water because it is denser than the water. In salty water, the added salt increases the water's density, causing the perspex block to float. This is due to the principle of buoyancy, where an object will float if it is less dense than the fluid it is in.
