We float or there is a possibility you can sink. You sink when you are heaver than the mass of the water. You float when you are lighter than the mass of the water.

Will an American coin float?
No, no US coin is light enough to float when dropped in water.
How do humans float in water?
its do do with how much oxyen we have inside us
How does salt help us to float?
It increases water density
Why cant you float in the air?
You are more dense than air. You float in water because water is more dense than people.
What are two bad things that insects do for us or to us?
a lot of insects carry diseases
Why is a person easily carried in water?
Because the air in our lungs and body makes us buoyant (float)
How does density affect us in your daily lives?
Density affects us in daily life by influencing the weight of objects, the amount of space they take up, and how easily they can move through different substances. For example, dense materials like metals are heavy and take up less space, while less dense materials like wood float in water. Understanding density helps in choosing appropriate materials for construction, designing transportation systems, and even measuring ingredients for cooking.
What does water saltness mean and?
Think of swimming. How your body stays afloat is usually because it is lighter than the water that it displaces. For some people with very very little body fat, if they stop swimming they will sink but for most of us we dont. Now think what would happen if the water was heavier? You would float higher in the water because you would weight even less in water so-to-speak Now, how does water become heavier? By adding in things like salt. So the more salt there is in water, the easier it is to swim in it and the higher you will float in it. If you were to swim in pool filled with pure clean distilled water, you would have to swim the hardest to stay above the water. If you swim in salt water like ocean water, you float higher in the water. If you swim in salt water like the Great Salt Lake in Utah, then you float relatively high in the water.
Do humans float on water?
YES!!! Human density is 0.97 of 100 for water. So since we are less dense than water , we will float. Added to which nature gives us a pair of 'water wings' , they are called 'lungs'. Yes!!! you can lie on the surface of water, but because our density is slightly less than watert , most of the human organism will immerse in water, but enough is left above the surface of water, for us to breath.
What does the economy do for the us?
It helps for the citizens to be able to buy nice things for themselves. For example to buy food, water, clothing, electricity, clothing and all of the basic needs for human life to carry on.
