Because saltwater is more dense than freshwater.
This had to do with density. When you put the egg into the water, it sinks as it is more dense than the water. However, if you add salt in the water, it becomes salt water and makes the water more dense than the egg so the egg can float. It is the same reason why people float in the dead sea. The dead sea is very salty and is more dense than humans. That's why we float so well in the dead sea.
Scientist think that lemons float because they have less density than limes. This is just observations that scientist have conducted, but they are still unsure.
it depends on the density of the object and the density of the liquid that it's in. if the density of the object is greater than the density of the liquid, then the object will sink. if the density of the object is lesser than the density of the liquid, the object will float.
circuit breakers ...fuses
this is because the sea is full of salt (as most people figure out after swallowing most of it) which acts as a buoyant that's why in the dead sea you float a lot easier as it is full of salt. in the swimming pool it doesn't contain as much salt. hope this helps :)
An object will float when it is less dense than the liquid around it. Because saltwater is denser than freshwater, it is easier for an object to float.
Tar is less dense than saltwater, so it will float on the surface of saltwater.
Seawater.Easy to understand explanation: Think about a person sitting on top of a pile of salt. They will stay on top of it much easier than if they tried to sit on water. Now of course the sea isn't all salt, but the more salt in it, the easier it is to float.Technical explanation: Because for an object to be able to float, the weight of the stuff it's floating in that it's displacing has to be greater than the weight of the object itself. For example, a cube that is 2 square centimeters and that weights 1 gram will float in anything that 2 square centimeters of weighs more than one gram. Because saltwater is heavier than freshwater, the water you displace weighs more and so you can float more easily.
It is easier to float in the sea because the saltwater is denser than freshwater in a swimming pool, providing more buoyancy. Additionally, the saltwater's buoyant force helps you float more effortlessly compared to freshwater.
Because salt is dense, so denser the water the better you float!
cuz saltwater is more dense than freshwater
Salt water is denser that fresh water, so a swimmer (and ships) float higher in saltwater.
When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt.Because objects float better on a dense surface, they float better on salt water than fresh water. The denser the salt water, the easier it is for objects to float on top of it.
Eggs can float in saltwater because the high density of saltwater makes the overall density of the egg lower than that of the water, causing it to float. In freshwater, the egg is denser than the less dense water and therefore sinks.
A person can float in saltwater because it is denser than freshwater. The salt in the water increases its density, making it easier for objects like the body to float. This difference in density is why a person can float in saltwater but not in freshwater.
Rubber typically floats in saltwater due to its low density. The buoyant force acting on the rubber is greater than its weight, causing it to float.
predicting would it be easier to control saltwater or freshwater blooms explain
