Buoyancy in water can be due to a number of factors. The biggst one being the difference in physical makeup between men and women. When swimming the heaviest part of our body is our pelvis which is why we generally more inclined to be in an up right position in water. (Generally for people who rarely swim).
Being the child bearers or the species, women tend to carry more fat around our pelvis and thigh area and because we have wider set hips we tend to float better.
Cultural differences can also come into play here as different ethnicities have a different type of genetic makeup. People of an Asian background are more likely to be narrower whereas people of a European background can be found to be more fuller figured.
To help with buoyancy all you need to remember is that because our pelvis is the heaviest part whatever we do to our head will affect our leg posionting and vice versa. A good head position for say freestyle would be to have your head under the water not just your face.
NOTE- I have tried my best to word this as good as possible but my apologies if I have offended anyone in my answer.Answer B
Yes, women do float easier then men because the women have more fat tissue than men and have a better distribution of it, their bones are less heavy and smaller, and their muscles are more flexible and lightweight.Answer C
Actually, for a man and woman who weigh the same amount, they have identical fat, bone, and muscle density. They just won't have the same amount of each. The prime difference is in percentage of body weight that is fat, as fat is significantly less dense than water (both muscle and bone being more dense than water). Even a woman in good shape will have at least 10% body fat, while a comparable man will have 5% or less.
Adding Salt to the water increases the density of the water, and therefore makes it weight more per capita. This in turn causes the salty water to push down with more force then water with no salt, causes things that may not float, to float, and things that already float in normal water, to float higher in salty water.
Objects float more easily in salt water, and the saltier the better. Any solid object placed on the surface of a liquid displaces its weight in that liquid (up to a maximum of the object's own volume). Saltwater, or any solution containing solutes, is more dense than plain water, so less of it is displaced, and objects will not sink as far into it, i.e. they are more likely to float rather than sink.
Salt water is more dense than pure water and so is sugar water. Salt and sugar are ripped apart when they are disolved in the water. With the salt and sugar in water, it makes the liquid more dense and thus the egg floats, or floats higher, in the water. Like the ocean, you float due to its salt content. If there was no salt in the ocean, you would not float as easily.
Your body fat has a lot to do with how well you will float but basically people can and do float. I personally don't float very well but with air in my lungs and on my back I float easily. Basically, it's because we are more dense than water. By breathing in air, our density becomes less than that of water and we begin to float. This is how people can stay afloat and how people can drown.
It is due to the fact that ponds are fresh water and the ocean is salt water. The high salt content causes you to float more easily as opposed to fresh water where you sink more readily. The Red Sea is a good example it has such a high salt content that you can almost float on the surface with little effort.
because the salt levels in the ocean are higher than those in a swimming pool. Basically, the water in the sea is more viscous than that in the swimming pool, meaning that it is more dense. This is because of the concentration of the water (it contains salt and many other substances that makes it more concentrated). Therefore, people can float more easily in the sea.
