When an object is less dense than the fluid it is immersed in, it will experience a buoyant force pushing it up. This is due to the pressure difference between the top and bottom of the object, causing it to float or rise. It is the principle behind why less dense objects float in more dense fluids, like a boat on water.
What else can I help you with?
Is saliva less dense than oil?
Yes, saliva is less dense than oil. Saliva is composed primarily of water, whereas oil is made up of non-polar molecules that are less dense than water.
Which rock is made up of less dense minerals like quartz and feldspar?
Granite
What can speed up light?
Travelling through a medium that is optically less dense. Vacuum is best.
What are convection winds?
As the air molecules heat up they move faster, spread apart and as a result the air becomes less dense. As it becomes less dense it will go upwards. Cool air will move to take the place of where the warm air was = wind! You have experienced this in the kitchen. When the stove is really hot and you open the door you will feel a blast of warm air hit you as it leaves the oven and goes upwards because it is less dense than the air in the kitchen
Why is water located above the earths crust but below the air?
Because it is less dense than the material that makes up the earth's crust, but more dense than the material that makes up the air.
How does air change the higher up in the atmosphere you go?
It becomes less dense.
Does the body density change in water?
No the density is like a solid like thing,humans,and places.
How is the earth like a density column?
Earth is like a density column, because the inner core is the most dense, and it gets less and less dense as you go up top to the crust.
How does air help to make a hot air balloon work?
Air has a certain density. A hot air balloon heats air inside the balloon which causes it to become less dense. This is because the hotter something is, the more space it takes up. Less dense things float on top of more dense things (think of oil on water). You get enough less dense hot air, and the balloon will float up on top of the cold, dense air.
A light was speeds up as it moves from a more dense to a less dense medium?
This is an example of refraction. When light moves from a more dense medium to a less dense one, it speeds up, causing it to bend away from the normal.
When dense cold air meets less dense warm air the air is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense cold air meets less dense warmer air the air is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense cold air meets less dense warmer air the warm is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
Why does the density of the atmosphere decrease with height?
The Earth's atmosphere declines with altitude.
Why won't a cork stay in place at a bottom of a pool?
it is less dense that the water so it is boyuant and will go up to the surface
What effects the layering of earths atmosphere?
the density and temperature of the layers. The farther you go up, the less dense each layer is.
Is saliva less dense than oil?
Yes, saliva is less dense than oil. Saliva is composed primarily of water, whereas oil is made up of non-polar molecules that are less dense than water.
