Why does water exert greater pressure on an object than does an equal volume of air?

If you were to take equal volumes of air and water and weigh them, Water would have a larger mass than air, because there are more water molecules than air molecules in the same volume.
Therefore, since Pressure = Force x Area, we need to find the force.
Since the water has a larger mass, it will automatically have a larger force than the air. So if it has a larger force, it will also have a higher pressure.

Pressure is equal to the amount of force exerted on an object divided by the volume over which the force is exerted?
Over the area not volume
What is equal to the volume of water an object displaces?
volume of water an object displaces is equal to the volume of the part of the object inside it
If an object float the volume of the displaced water is equal to the volume of the whole object?
False
If an object floats the volume of the displaced water is equal to the volume of the whole object?
False - Apex
If an object floats the volume of the displacement water is equal to the volume of the whole object?
False - Apex
How is fluid used to lift heavy objects?
Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.

What is true about the mass and volume of all sinking object?
If an object sinks in water, then its mass is greater than the mass of the volume of water that the object displaces. (That could be equal to or greater than the object's actual volume ... a drinking glass displaces more water than the volume of glass in it until the water washes over its rim. A canoe, a bass-boat, and a ship are designed to displace more water than their actual volume.)
If an object float the volume of the displaced water is equal to the volume of the whole object?
False
Is it true that If an object floats the volume of the displaced water is equal to the volume of the portion of the object that's underwater?
the weight of the displaced water is equal to the weight of the object
What is the relationship between the volume and the buoyancy?
Density = mass / volume. An object will float if it has less density than the fluid in which it is placed. The buoyant force is equal to the volume (this may be the submerged part of the volume) times the density of the displaced fluid.
How can an irregular volume be measured?
By placing the object in water and the volume of water displaced is equal to the volume of the object immersed
What is the relationship of volume of water to its mass?
volume in litres is equal to its weight in kgs 1000ltrs is equal to 1000kgs
Why do aircraft carriers float in water if they are made of materials that have a greater density than water?
Archimedes put it that "Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid that is displaced by the object."So our aircraft carrier will only displace a volume of water equal to the weight of the ship. But the volume of the ship is much greater than that volume of water. So it floats.
If an object floats the volume of the displaced water is equal to the volume of the whole object?
False - Apex
If an object floats the volume of the displacement water is equal to the volume of the whole object?
False - Apex
