What part of the block of wood remains immersed in water of density 1000kg per cm cube when the block of wood placed in water has density 700 Kg per m cube?
-- The aggregate density of the wood block is 700/1000 = 0.7 the density of water.
-- So, as soon as the wood has displaced 0.7 of its volume in water, it has displaced
its entire weight in water, and floats.
-- The wood floats with 0.7 of its volume below the surface and 0.3 of its volume above it.

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.
How did Archimedes solve the King's problem?
He discovered the difference in density between gold and silver when placed under water, and noticed that the crown was not pure gold. The crowns maker was later beheaded.
Another word used for placed?
Situated, Located, Positioned, Set, Placed, Sited, Found
What would happen if a substance with a density of 0.95gml was placed in oil?
That would depend upon the density of the oil (which will depend upon temperature), how absorbant of oil the substance was and how deep the oil is. Assuming the substance does not absorb any of the oil then depending upon the oil various things would happen: In some oils such as Car oils, Coconut oil, Crude oil California, Linseed oil which all have a density less than 0.95 g/ml the substance would sink (unless the oil was not deep enough in which case the substance would sit on the bottom of the container and appear above the surface of the oil). In other oils such as Castor oil, Crude oil Mexican, Rosin oil which all have a density greater than 0.95g/ml the substance would float.
Does the tendency for an object to sink or float have to do with the object's density?
Yes. The object will sink if its density is greater than the fluid it is placed in.
What is density displacement?
Density displacement refers to the displacement of an object or substance due to the difference in density between two mediums. This phenomenon occurs when an object is placed in a fluid and experiences a buoyant force that counteracts gravity. The displaced volume of fluid is equal to the volume of the immersed object.
What are facts about buoyancy?
Buoyancy is the upward force exerted on an object immersed in a fluid, such as water or air. The buoyant force is equal to the weight of the fluid displaced by the object, according to Archimedes' principle. Objects will float if their density is less than the density of the fluid they are placed in, and sink if their density is greater.
Do heavy things always sink and light things always float?
No, whether an object sinks or floats depends on its density compared to the density of the fluid it is placed in. An object with a lower density than water will float, while an object with a higher density will sink. The weight alone does not determine if the object will sink or float.
What is the density of an object with a mass of 5g that when placed in a graduated cylinder raises the volume of water from 30mL to 45mL?
The volume of the object displacing the water is the difference between the final volume (45mL) and the initial volume (30mL), which is 15mL. Since 1mL is equivalent to 1cm^3, the volume of the object is 15cm^3. To find the density, divide the mass (5g) by the volume (15cm^3) giving a density of 0.33 g/cm^3.
When this material is placed in a container of water it sinks to the bottom of the container compared to the density of water the density of the material is?
The density of the material is greater than the density of water if it sinks to the bottom of the container when placed in water.
How do you think the liquid density affects the buoyancy of objects placed in a liquid?
The density of a liquid affects the buoyancy of objects placed in it according to Archimedes' principle. When an object is immersed in a liquid, the buoyant force acting on it is equal to the weight of the liquid displaced by the object. Therefore, if the liquid has a higher density, it can support more weight and provide greater buoyant force. Conversely, a less dense liquid will provide less buoyant force for the same volume of liquid displaced.
What is the relationship between density and volume and 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.
Why does anything sink?
An item will sink if its overall density is greater that the density of the fluid in which it is placed
Sinking and floating?
An object sinks if it is denser than the liquid it is immersed in, causing it to displace an amount of liquid that weighs less than the object itself. Conversely, an object floats if it is less dense than the liquid it is placed in, allowing it to displace a sufficient amount of liquid to support its weight. Archimedes' principle explains this phenomenon.
What is happens to an object when placed in water if the density is below one?
If an object with a density below one is placed in water, it will float. This is because the density of the object is less than that of water, causing it to be buoyant and float on the surface.
WHAT happens to a solid object with a density that is less than the density of water when it is placed in water?
It floats
