Why the weight of the objects are greater in the air than their weights in the water?

It is because the buoyancy of water is greater than that of air.
In other words, the force pushing up on an object is equal to the weight of the same volume of whatever the object is in as the volume of the object. For example, a 1'x1'x1' cube submerged in pure water has an upward force on it of 62.4 pounds because the density of water is 62.4 pounds per cubic foot.

How can you make a substance with greater density greater than water float?
if the substance of the element has greater density you can make it float by carving it out so weight over volume of the object is lighter in effective density
Can plywood float?
It depends on theplywood density if it is denser then water then you would have to make a shape causing it to displace an equal or greater amount of water in weight for it to float.
Which weighs more 155 pounds of flour or 155 pounds of water?
Flour and water are two substances whose weights are referenced to the same system of weights ... the avoirdupois system. Therefore the "pounds" used for each of them are the same pound. So 155 pounds of flour and 155 pounds of water have exactly the same weight, namely 155 pounds. There's no way to tell them apart using a scale.
What has greater mass 1mL or 4mL?
our bodies are mainly composed of liquid (water), which is measured in ml's, so 4ml's has greater mass eventhough is not solid, it's still part of the weight added to anything solid or space.
Are objects that sink are more dense than water?
Yes, the weight of the object doesn't matter as much as the density. For example, a pebble will sink in water because it is very dense, yet a log won't because it's not as dense as water.
What objects float in gasoline?
objectsfloats on water, oil and kero depending on the objects density or the objects weight.
What happens when the water around objects have a force greater than the object's weight?
The water around floating object's is a measure of that object's "Displacement". For the object to float the weight of displacement must equal the object's weight. If the water around an object is of a greater weight than an object's displacement, then the object will sink.
What happends if the weight of an object is greather than the weight of the water?
I assume you mean "What happens if the weight of an object is greater than the weight of the water it displaces." If so, the answer is simple, it sinks. If an objects weighs less than the weight of the water it displaces, it floats.
Two different objects are completely immersed in water and undergo same loss in weightis it necessary that the weights of these objects in air be also the same?
Ooooh, tricky question. You said that each object "lost" the same amount of weight in water, and that means that the two objects were the same size (i.e., they displaced the same amount of water when submersed, therefore the same weight loss), but it does not mean they weighed the same to start with. Regardless of their intitial weights, they will lose an amount equal to the weight of water they displace. So, no, the two objects do not necessarily weigh the same in air, but they might. There is no information here to tell you whether they do or do not. Ray
What objects sink in the water?
Those objects that have a greater density than water will sink in the water. This comes from Archimedes' principle which states that a floating object displaces an amount of water equal to the weight of the object. If the object has a greater density than the water, then it would displace more water than is possible by its volume, so it sinks.
Why do large cruise ships float in water?
This is because they displace a volume of water which has a weight equal to their weights. The upward upthrust is equal to their weights (upthrust = weight of fluid displaced)
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.
Everything in or on water pushes some water aside even if just a little bit. This is called .?
This is called "displacement", as the weight of water that moves is equal to the weight of the object on the water. Heavier objects displace more water. If the total weight of the object is greater than the water displaced by its volume, it is denser than water, and sinks.

Why can water support objects that have greater densities than water?
Surface tension.
Do liqiuds have weight?
yes, to prove this, there are weights that can be filled with water and some can be 32 pounds of water.
