An object will float in a substance if it is less dense that it, and if they are more they will sink. Water is 1g/mL, and most people are quite similar to this (so close that usually if someone in water breathed out, they sink, breath in, they float). What makes the difference is not how much someone weighs, but their density, which depends on how much muscle and fat they have. Fat is actually less dense than water - so having more fat will actually make a person more bouoyant. Muscle is more dense than water so a person having more muscle will sink. So a person weighing 240 pounds could float while a 160 pound person could sink - it depends on what their body is like.
Because of their density: People with a lower body fat percentage (fat is less dense than water) sometimes cannot stay on the surface of the water without motion to propell themselves upwards, although most people *do* remain at the surface if they relax and lean back.
Bone is considerably more dense than water, muscle is a little more dense, and fat less dense.
If the weight of water you displace is less than your own weight, you will sink.
What else can I help you with?
Do all fruits float in water.?
== Yes because the volume of water displaced by a cherry is enough that the buoyant force of the water is able to counteract the force of the cherry's weight.==
Do peanuts float in fresh water?
Yes. The salt stabalizes them in the water. If you have ever heard of the dead sea, anything really can float in there. If there is salt in water a peanut can float.
Why do some objects float and others dont?
Because some objects are a lot denser than water so the sink and others are less denser so they float
Why do some people float while other people drown?
Oh, dude, it's all about density! So, like, if you weigh less than the water you displace, you float. If you're denser than the water, well, you're gonna sink like a rock. It's just science, man.
Can a hockey puck float on water?
No, because a hockey puck has a higher density than water. In some cases, objects with higher density than water can still float on the water, if they are small enough to avoid breaking the surface tension of the water. This is also the case if the object's mass is distributed across a large enough area, so you could float a penny on water if you put it down flat across the water, but it would not float if you dropped it in on its side. You also could not float that penny if you melted it down and made it into a sphere, for example.
Do all fruits float in water.?
== Yes because the volume of water displaced by a cherry is enough that the buoyant force of the water is able to counteract the force of the cherry's weight.==
Does salt water float?
On some liquids it will float, on others it will not.
Do flowers float?
Some types of flowers, like water lilies, have air pockets in their stems and leaves that help them float on water. However, not all flowers float – it depends on their composition and structure.
Why can't some people float?
This is easy. Muscle does not float. If the person has body fat the person will float, the more fat the better the person floats. The less fat, the less a person floats.
Will the people be able to float on water if the strength of earth's gravity is doubled and Why?
No, the increased gravity would make it harder for people to float on water. The extra force pulling them down would make it more difficult for them to displace enough water to stay afloat without some external support.
Why don't mostsubstance float in air if they float in water?
It is waters greater density than air that allows some substances to float on water.
Do peanuts float in fresh water?
Yes. The salt stabalizes them in the water. If you have ever heard of the dead sea, anything really can float in there. If there is salt in water a peanut can float.
What is the answer to the question does an object float in saltwater freshwateror neither?
It's far from clear what the actual question is. Some objects float in both salt and fresh water, some objects float in neither, and some objects float in one but not the other. Any object that floats in fresh water will float in salt water, but the reverse is not true.
What are the substances that float in water?
Substances that float in water typically have a lower density than water. Some examples include wood, oil, plastic, and cork. These substances are able to displace enough water to generate an upward buoyant force that keeps them afloat.
Why do people float although they have a larger density of water?
In water, you mean? If an object has a larger density than water, it will float; otherwise, it won't. From my own experience, when I inhale, when my lungs are full of air, I float without effort. When I exhale, I start to sink - and need some effort to remain at the surface.
Does sulfur sink or float?
Sulfur sinks in water because it is denser than water.
What type of objects will float on top of water?
The types of objects that will float on water are foil, most rubber, and some plastic.
