Why does the heating in a hot air balloon allow it to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and float upwards. This is due to the principle of buoyancy, where objects that are less dense than the fluid they displace will float in that fluid.
Which fluid produces greater buoyancy air or water?
Water produces greater buoyancy than air because water is denser than air. This means that an object will displace more water and experience a greater buoyant force when submerged in water compared to when surrounded by air.
Why does something sink or float according to buoyancy?
Density (mass x volume) of the object. If the object is less dense (helium in air, or foam in water) than the fluid in which it is placed, it will float. Likewise, if the object is more dense (lead in water, or water in air), it will sink.
Who discovered that objects can displace water?
The principle that objects can displace water was discovered by the ancient Greek mathematician and physicist Archimedes. This principle is known as Archimedes' Principle and it states that an object submerged in a fluid will displace an amount of fluid equal to its own volume.
Is buoyant force exerted by air also?
Yes, that is what makes hot air balloons and helium balloons float. Since air is far less dense than water, you need to displace far more air to get an object that floats on water to float in air. That's why hot air balloons are so huge.

How much fluid dose a submerged objects-displace?
an amount equal to the volume of the object.
How does Archimedes' principle relate the buoyant force acting on an object to the fluid displace by the object?
The weight of the bouyant force and the fluid displaced by the object are equal.

When an object is placed in a fluid the object weighs less by an amount equal to the weight of the displace fluids?
This is corrent
Does a air potato affect the environment?
Yes it does. Air potatoes have the ability to displace other native plants.
Is buoyant force exerted by air also?
Yes, that is what makes hot air balloons and helium balloons float. Since air is far less dense than water, you need to displace far more air to get an object that floats on water to float in air. That's why hot air balloons are so huge.
Which fluid produces the greater buoyancy force - air or water?
Buoyant force is dependent on the density of the fluid. Since water is denser than air (by a lot), an object immersed in water will experience a much greater buoyant force than one surrounded entirely by air.
Why water displace the air?
Water can displace air when poured into a container because water is denser than air. The molecules of water are packed more closely together, so when water is poured into a container, it pushes the less dense air out of the way, causing it to rise up and be displaced.
When 2 shafts are parallel to each other at a certain distance and no gears or belts are to be used then what is the coupling to be used to transmit the motion between the shafts?
Air or fluid pressure... If you put cylinders in the shafts and connect them through pipes or tubes, then you can transfer pneumatic or hydraulic pressure form one to the other. As one cylinder is lowered in one shaft, it will displace the fluid (air being a fluid) and because that fluid would have no escape, it would force the cylinder in the other shaft to rise.
