What does volume and mass have to do with flotationn?
The density of an object is its mass divided by its volume. If that is less than the density of water, it will float; if greater it will sink
What will happen if an object has a density greater than water?
If inserted into the water as a solid "blob" then it will sink - unless it dissolves first. But, if because of the shape, the mass of water displaced by whole object is greater than the mass of the object, it will float - just as ships made of metal do.
What has to have more density for an object to float on water the object or water?
Normally the water - to float and object has to displace a volume of water equal to its mass. If its density is greater than that of water, the maximum mass of water it can displace is its own volume which, as the water is less dense that it, will have less mass than the object and it will sink. However, for small light objects the surface tension of water comes into play - it is possible to float a steel sewing needle (with a density greater than water) on water by gently dropping a clean needle on its side onto the water surface so that it does not break the surface tension. With a needle floating, adding a few drops of washing up liquid to the surface reduces the surface tension and the needle will then sink.
How do you know an object has a density greater than water?
If an object placed in water sinks - then it has a density greater than water.
If object has mass of 3.5gml is placed in water what will happen?
I think you mean to say density. If I'm right, it'll sink.
Can you use density of an object to predict whether it will float or sink in water?
Yes, you can use density to predict whether an object will float or sink in water. If the density of an object is less than the density of water (1 g/cm³), it will float. If the density of an object is greater than the density of water, it will sink.
If an object sinks when being placed in water its density is?
To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.To sink, the object's density must be greater than the density of water.
Why does an object float or sink when placed on the surface of water?
An object floats in water if the object's density is less than water's...Conversely, an object will sink if it's density is greater than that of water.
How do things sink and float?
it depends on the density of the object and the density of the liquid that it's in. if the density of the object is greater than the density of the liquid, then the object will sink. if the density of the object is lesser than the density of the liquid, the object will float.
If you the mass and volume of an object how can you predict whether it will float or sink in water?
Calculate the density (mass divided by volume) of your object. If the density is less than that of water - which has a density of about 1000 kg per cubic meter - then it will float; if the density of your object is more, it will sink.
How can you use density to determine if an object will sink or float a fluid?
If the density of an object is lower than water then it will float, if the density is higher it will sink.
What will an object do if its density is greater than that of water?
If an object's density is greater than that of water, it will sink in water. This is because the buoyant force acting on the object is less than its weight, causing it to sink to the bottom.
What affects how an object sink and float in water?
the density of the object
An object has a density of 2gcmcubed will it sink or float?
It will sink. Water has a density of 1 gm/cm3.
does a coin sink or float?
The reason the pennies sink in water is because of an idea called density. The pennies have more density than the water, and so the pennies sink. Anything with more density than water will sink in water, but other objects that have less density than water will float.
What will happen to a solid object made from matter with a greater density that water when it is dropped into water?
The object will sink in water because its density is greater than that of water. The buoyant force acting on the object is less than its weight, causing it to sink.
Will an object with a density of 0.97 grams millimeters float or sink in water?
The object will sink in water, as the density of water is 1 gram per cubic centimeter. Since the object's density is less than that of water, it will not displace enough water to float.
