Why does an object seem lighter in water?
because of the upthrust in water it weighs less and floats. An object in water will recieve an upthrust equal to the weight of water it displaces . submarines when neutrally ballasted could hang by the periscope that is just under the water raise periscope sub sinks down as water covers periscope starts to rise again, Any floating object displaces its own weight of fluid.
Why does water rise when you put an object in it?
Water vapor is a gas made of one oxygen atom and two hydrogen atoms. The surrounding air is a gas mixture consisting mostly of nitrogen (two nitrogen atoms). Water vapor is lighter than air and therefore will rise until it has time to mix with the surrounding air. The resulting moist air is lighter than any nearby dryer air at the same temperature, and so will also rise.
How does the density of a rock affect its ability to float?
If the density of ANY object is less than 1.00, then it will float in fresh water. If the density is greater than 1.00, the object will sink in fresh water. If the object's density is precisely 1.00, it will be "neutrally buoyant" and will neither rise nor sink; it will remain at whatever depth you place it.
When will the object sink in the water?
A substance will sink in the water if it has more density than the density of water. The density of water is one. In order to any thing float in on the water it should displace the equal amount of water to the equal number of its mass. The substance with denser than water will sink in the water.
Why does buoyant force vary with depth of the submerged object?
The buoyant force is equal to the weight of water displaced. For a dense object, such as a coin or a bowling ball, the weight of the object is greater than the buoyant force and the object will sink if you let go of it. For a less dense object, such as an ice cube or a block of balsa wood, the buoyant force is greater than the weight and you can feel it pushing the object toward the surface, resisting your attempt to hold it submerged. If you let go, the object will rise up and float.
If a object has air inside will it sink?
If an object has air in it than no it will not sink in water because air is less dense than water so it will rise in water.
What determines an object will sink or float?
The Density of the object as long as its .99 grams then it will float because the object has to have less density than water in order to rise above the water.
When water is heated why would a submerged object rise faster?
Since you asked, I don't think it would.I think a submerged object would rise slower in hot water than in cold. The densityof the hot water is less than the density of cold water. So whatever volume of fluidthe submerged object displaces has less weight, and the buoyant force on thesubmerged object is less than it would be in cold water.That's my story, and I'm sticking to it.Another answer:I agree. What makes you think an object will rise faster?
What is water displacement?
Water displacement is simply when something (e.g. a block) is put into water, and the water level rises. This is because the block is taking up space, and the water has to move somewhere, and the only place to go is up.
What is the Archimedes principle of displacement?
I think it is the volume displacement. When you put an object into a container with a known volume of water, the water will rise, and that change of volume is the volume of the object you introduced into the container.
What happens to density when an object is frozen?
With the exception of water, the particles of an object move closer together and become a solid. Being closer together makes the density rise once it becomes frozen but the density won't rise if the temperature is lowered and the object is already frozen. When water freezes, the density lowers, making ice float.
Is rise used in the form of a direct object?
Yes, the noun 'rise' can function as the direct object of a verb. Example: We have witnessed a rise in public awareness following the tragedy. (the noun 'rise' is the direct object of the verb 'have witnessed')
What do you do with the soda in mission 8 on club penguin?
You toss it into the water at DR. Calico's water tank. Then wait for it to rise. (Sorry, the answers kind of random.)
How do you find volume using displacement?
You can find volume by using displacement:The way you can do this is by filling up a beaker of a graduated cylinder or other measuring device with water.You drop some water in there and then you record how much you dropped. Then you put an object in making sure the object is completely submerged.The water will rise, and you record how much it rose, in Units of Volume (cm3).Then you subtract how much water you put in with the rise of the water when the object was put in.And that's how you find volume by displacement.

What happens to an object's temperature when you heat?
The temperature of the object will rise because of the heat.
