The density of styrofoam is lower: about 0.028 to 0.045 times that of water.
how much is styrofoam unit weight?
No, they do not.
Yes, it is.
The density of styrofoam is 100 kg/m3You can check out the density of other items by visiting this site.http://www.monachos.gr/en/resources/Thermo/density.asp
High density styrofoam installed in sheets can be extremely good insulation.
The denser the styrofoam, the greater it's load bearing ability.
Styrofoam absorbs gamma rays and is compressed. Because the styrofoam surrounds the reactants, they is compressed to the density needed to sustain fusion.
No, it floats because of buoyancy.
The coin has a greater density than water. Styrofoam has less density than water. It's as simple as that.
Polystyrene is a plastic that can be made into many products, which can be dense, or can be in the form of a low density foam, called Styrofoam.
The weight of styrofoam depends on the density of the styrene hydrocarbon from which it is manufactured and the volume of air bubbles trapped in the foam.
No. A stone has much higher density than a styrofoam mattress, but much less mass.
Density is how much "stuff" is inside something. A piece of styrofoam is not as dense as a bowling ball because the styrofoam has lots of air bubbles in it and the ball is solid. Collect different materials and let them pick them up and see how they compare.
It will float. Like styrofoam or wood on water.
polystyrene / styrofoam plastic wood / cork / ice
There are several. They would include displacement, buoyancy, and density.
If something has a low density, it will weigh little for its volume. For example, feathers, styrofoam, and balsa wood all have low density. They seem light compared to how much room they take up.
No density does not depend on size. Density depends on what it's made of. For example, if you put a small rock in a bucket of water it will sink, however, if you put a large Styrofoam ball in the water, it will float!
Mass and Volume are related through Density where: Volume x Density = Mass As for your question, styrofoam is a brand name that we use to describe any polystyrene foam. As such, its density varies depending on the manufacturer. From what I found in this answer: http://wiki.answers.com/Q/What_is_the_density_of_styrofoam it looks like you would have anywhere from 50 to 400 cm3 (50 to 400mL)
Not at all. You can paint styrofoam or granite any color you want. Also, gold and blond hair have similar color but substantially different density.
The correct spelling is 'styrofoam'.
A 1-inch cube of stone . . . high density. A 1-inch cube of styrofoam . . . low density. A 1-inch cube of air . . . even lower density.
Styrofoam is an insulator.
