Tutor description

Your bodies density is the same whether you are in seawater or freshwater but the actual density of the water itself is greater in the seawater because with the salt in there there are more particles of substance packed into one area. One of the elementary rules of density is that the denser object will sink faster than the less dense one.

Your bodiesdensityis the same whether you are in seawater or freshwater but the actual density of the water itself is greater in the seawater because with the salt in there there are more particles of substance packed into one area. One of the elementary rules of density is that the denser object will sink faster than the less dense one.You can look at it like a fraction...Say your density is 20 units and the density of saltwaters is 60 and freshwaters is 50.20/50 = rate that you sink in the freshwater20/60 = rate that you sink in the saltwater20/50 > 20/60 so the rate that you sink in freshwater is greater than the rate that you sink in saltwater.Density= Mass / VolumeMass is determined by the effect of gravity on an object. The higher up you go the weaker gravity goes and if gravity gets smaller than so does mass. A smaller mass divided by the same volume gives you a smaller number, hence the decrease.t is easier tofloatobjects in seawater than in fresh water. Many humans can "float" in seawater but not fresh water. The reason is that water with salt in it, is more dense. So objects that cannot float in fresh water may be able to float in seawater. Floating refers to having a substance rise to the top of another substance. For example, a balloon with helium will float in air because it is lighter (or less dense). If you forced an object to go under the water and let it go, it will float to the top.Why a Ship FloatsBecause of its shape, a steel s
