If an object's density is is less than that of the fluid what will happen?

The object will float in the fluid because it is less dense than the fluid. The principle that governs this behavior is Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object.


Why do things float and some things sink?

Objects float or sink based on their density relative to the fluid they are in. If an object is less dense than the fluid, it will float; if it is more dense, it will sink. This is due to the buoyant force acting on the object, which is the result of the pressure difference between the top and bottom of the object.


What happenes to the density of a fluid as it becomes hotter?

The hotter part of the fluid becomes less dense and rises to the top. Where as the colder part of the fluid will be more dense and will sink to the bottom.


What happens to the density to the fluid as it becomes hotter?

The hotter part of the fluid becomes less dense and rises to the top. Where as the colder part of the fluid will be more dense and will sink to the bottom.


How is heat energy transferred with convection?

Heat energy is transferred through convection when a fluid (liquid or gas) is heated, causing it to expand and become less dense. The warmer, less dense fluid rises and is replaced by cooler, more dense fluid. This creates a circulating flow, transferring heat energy throughout the fluid.


When an object is less dense than the fluid is is in the object will float or sink?

An object that is less dense than the fluid it is in will float. This is because the buoyant force exerted by the fluid on the object is greater than the force of gravity pulling the object down.


What is a covection current caused by diffences in what?

Convection currents are caused by differences in density. Warmer fluid is less dense, so a fixed volume of the warmer fluid is lighter. Colder fluid is denser, and so heavier in a fixed volume. The colder, denser fluid presses down and falls below the less dense fluid, which floats up to the top of the fluid. Often, there is a heat source that the bottom of the container, so the fluid at the bottom, which was more dense, warms up and becomes less dense. At the same time, the fluid at the top cools down and becomes more dense, and so the cycle repeats, forming a convection current.


Can a viscous fluid be less dense then fresh water?

Yes, for example oil is less dense than water even though it is more viscous.


How does density cause things to move?

Density can cause things to move when a less dense object is placed in a more dense fluid, such as water. The less dense object will float because it displaces an equal weight of the more dense fluid. This creates an upward buoyant force that pushes the object to the surface.


Does an object that is more dense than the fluid on which it is immersed floats to the surface?

No, an object that is more dense than the fluid it's immersed in will sink to the bottom. Objects float when they are less dense than the fluid they displace, allowing them to be buoyant and stay on the surface.
