What can you infer about the density of a material if a sampleof it floats in water?
That the material's density is less than the density of water.
What is the property of that makes something sink or float?
More or less density of the material compared to the density of the water.
Does the density of material change when the material expands?
Ice has expanded when it turned from water into ice. Ice floats. This shows that the density of the ice is less than water.
How does density of material affect burn rate?
All else being equal, for the same material, the more dense it is (i.e. the less air it contains) the slower it will burn.There is no overall general rule relating density of different substances and their burn rate.
What factors determine how heavy an object can be and still float?
An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.
What can you infer about the density of a material if a sampleof it floats in water?
That the material's density is less than the density of water.
What type of material floats?
Any material that has less density than the liquid on which it is supposed to float.
What is the property of that makes something sink or float?
More or less density of the material compared to the density of the water.
What can you infer about the density of a material if a sample of it floats in water?
it is less dense.
Does the density of material change when the material expands?
Ice has expanded when it turned from water into ice. Ice floats. This shows that the density of the ice is less than water.
Why does a less dense material float in a more dense material?
density is mass per unit volume so the less mass per cubic(what ever measure) the less buoyant.
When a beam of light passes at an oblique angle into a material?
The result of a beam of light passing through a material relies entirely on the optical density of the material. If its density is lower than air, then the angle of incidence will be less (more acute) than the angle at which it enters. The opposite is true for a material with higher optical density.
Is the density of a white dwarf greater or less than material on earth?
millions of times grater
Would the density of an ice cube have the same density as an iceberg the size of an entire school?
I would expect it to have more or less the same density, since it is made of the same material.
The density of a liquid form of a material is always less than the density of the solid form of that same material?
Yes true, however this is not true of H2O or water. Water in solid form is actually less dense than its liquid form. That is why ice floats on water.
What causes to the temperature and the density of the material between point b and c?
the heat makes the density less or more dence depending were it is in the earths layers
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.
