When you breath out under water, you are releasing the air from your lungs. Air is far less dense than water, which is why things that are filled with air float. So if you breath in, and then go under water you will float toward the surface. However, if you breath out and release that air in your lungs, you lose the buoyancy that the air was giving you. Thus causing you to sink...

What do you decrease by taking a deep breath in the water to float?
Your density.
Why do you tend to float lower in the water when you exhale?
You tend to float lower in the water when you exhale because you are getting rid of air. This air is buoyant and helped you to float higher.
What are objects that easily float?
Anything that has a density that is lower than water will float. The lower something's density is, the more buoyancy it will have.
Can a stillborn baby's lungs float?
No, the baby never filled them with air from their first breath, therefore they are fluid filled...and won't float.
Ice float on top of water?
Ice float on water because the density is lower.
Why does a icebreg float?
water is the only substance on earth where its density is HIGHER when liquid, and LOWER when solid. a substance will float on top of another if its density is lower than the other substance. so because the ice has a LOWER density it will float on top of the water
Why will a cork float in a swimming pool?
A cork has a low density. It is lower then water. That causes it to float.
If something has low density in it will it sink or float?
If something has a lower density than the substance it is in it will float.
Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
Why can you float?
the density of your body is lower than water....:)
How can you use density to see if an object can float?
Usually, an object can float if it has a lower density than the liquid it is in.
Does iron float in oil?
Iron will float in oil in most cases. However, for iron to float in oil, it must have a density which is lower than the oil.
