Water has a density of 1 - therefore anything that sinks in water (e.g. iron with a density of 7.874) has a density higher than 1 and anything that floats in water has density less than 1.

Why does an object float based on density?
--Objects sink in water if they have a higher density than water and float if they have a lower density than water. Density is mass per volume of an object (usually measured in grams per milliliters, or g/mL)-- a denser object, such as a brick, will have a higher mass per volume than a less dense object, such as a sponge. The density of water is 1 g/mL, so anything with a density greater than 1 g/mL will sink, and anything with a density lower than 1 g/mL will float.
How can you predict if an object will sink or float in a fluid?
Based on its density. For example, waters density is 1 g/mL. If something has a density greater than 1 g/mL it will sink in water. If it has a density less than 1g/mL it will float in water.
What is the density of water at sea level?
At sea level, fresh water has a density of 1. 0 grams per milliliter. Seawater has a higher density than fresh water, 1. 025 g/ml.
How does cerebrospinal fluid contribute to buoyancy?
1- gravity of cerebrospinal fluid= gravity of brain 2- density of cerebrospinal fluid is higher than density of brain
How would you know if something would float on water?
Compare the density of the object in question to the density of water. If its density is less than water, it will float. For example, oak floats because its density is 0.7 g/cm³ and the density of water is 1 g/cm.If the density of an object is greater than water, it will sink.
Do materials with high density float or sink?
This depends on what the material is floating or sinking in. If an object in water that has a higher density than water will sink, but if it has a lower density it will float. For example, water has a density of 1.00 g/mL so if you put something with a density higher than 1 g/mL into it it will sink, but if the material you put in it has a density lower than 1 g/mL it will float.
How can you use the density of an object to predict weather it will sink or float?
if the density of the object was higher than 1 then it will sink if less than 1 it will float in water....
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.

What does japan has a very high population density mean?
Having a high population density means that there are more people living in a certain distance, for example Japan would have a higher population density if 1000 people lived in an area of 1 km squared. The higher the number, the higher the population density.
Does platinum float?
No. the density of platinum is 21.456 g/ml, which is much higher than the 1 g/ml density of water.
What two properties must you know to determin density?
Density is a measure of mass to volume. The density of water at 4C is 1 g/ml. So to determine density of a substance you need to know the mass and the volume. Any density higher than 1 will sink in water and any density lower than 1 will float.
What substance has a density less than 1 gmL?
For example ice and lithium.
An object with a density of 5.5gml is put in water what will happen to the object and why?
it will sink because it has a higher density than water which is 1 g/ml
How can you predict if an object will sink or float in a fluid?
Based on its density. For example, waters density is 1 g/mL. If something has a density greater than 1 g/mL it will sink in water. If it has a density less than 1g/mL it will float in water.
How can you use density to determine whether an object will float or sink?
If any object has a density higher that 1 it will sink because water has a density of exactly 1. If the density is less than 1 it will float. Here is the formula for density...D=m/v or density equals mass over volume.
Why does sodium chloride sink?
1. Because the density of sodium chloride is higher than the density of water. 2. Sodium chloride is soluble in water.
