Polystyrene is a common plastic that most of us encounter dozens of times a day in our travels, most often in packaging. The thing about polystyrene is that it has a number of forms (chemical structures). Consider this chemical formula:
C6H5CH=CH2
This is (monomer) styrene. If we link a bunch of these together, we end up with poly (many) styrene. Consider this chemical formula:
(C8H8)n
This depicts the basic (monomer) styrene with the subscript n to denote that a number of different molecules can be made up. And if you guessed that these molecules have different densities, you'd be correct. In general, the density of polystyrene varies from about 1.06 to 1.12 g/cc, so there is no "true" or precise density for polystyrene.
What else can I help you with?
How does 1kg of lead have the same density as 1kg of polystyrene?
Both 1kg of lead and 1kg of polystyrene have the same mass, despite lead being much denser than polystyrene. Density is defined by mass divided by volume, so if the mass is the same, the volume must differ to maintain the same density. In this case, the volume of lead will be significantly smaller than the volume of polystyrene, making them have the same density.
Is polystyrene heavy?
polystyrene is not heavy can be heavy in certain places though
What is the density of thermocol?
The density of thermocol or polystyrene is 1.64 g/cm3. it can vary due to the mass and volume of the object, the density usually ranges from 5kg/m3 to 12kg/m3.
Does 1kg of lead take up more space then 1 kg of polystyrene?
No, 1 kg of lead will take up less space than 1 kg of polystyrene because lead is denser than polystyrene. Density is the amount of mass per unit volume, so lead, being denser, will occupy less volume compared to the same mass of polystyrene.
Can scientists use the measure of density to tell if something will float. False True?
True. Scientists can use the measure of density to determine if an object will float or sink in a fluid. If the density of an object is less than that of the fluid, it will float; if the density is greater, it will sink.
How does 1kg of lead have the same density as 1kg of polystyrene?
Both 1kg of lead and 1kg of polystyrene have the same mass, despite lead being much denser than polystyrene. Density is defined by mass divided by volume, so if the mass is the same, the volume must differ to maintain the same density. In this case, the volume of lead will be significantly smaller than the volume of polystyrene, making them have the same density.
Is polystyrene less dence than water?
yes polystyrene is ls less dence than water because it floats
What is the density of hips?
High-Impact Polystyrene, HIPS´ve a density = 1,06 gr/cc
Is polystyrene heavy?
polystyrene is not heavy can be heavy in certain places though
What is the density of thermocol?
The density of thermocol or polystyrene is 1.64 g/cm3. it can vary due to the mass and volume of the object, the density usually ranges from 5kg/m3 to 12kg/m3.
Is expanded polystyrene a thermosetting or thermoforming plastic?
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
What is the unit cost of polystrene?
Polystyrene is often sold in bulk on a m3 (cubic meter) price in Europe The cost is also effected by the density of the polystyrene. That is assuming your talking of expanded polystyrene foam, polystyrene is also available in hard plastic sheet form. dunno
What is the density of polystyrene foam?
Answer: The raw material of the Polystyrene has a density of around 1.05 g/l, or kg/m3 . which is a little bit more than water's Regarding the processed material there are two main types of polystyrene density-wise;EPS = Expanded PolyStyrene:most used in the range of: 10 - 50 g/lEXPS or XPS = EXtruded PolyStyrene:most used in the range of: 25 - 45 g/l
What are the 7 classes of plastic?
The seven types of plastic are: Polyethylene terephthalate, High-density polyethylene, Polyvinyl chloride, Low-density polyethylene, polypropylene, Polystyrene, and an unnamed category consisting of plastics that do not fit into the other categories. Polystyrene is often called Styrofoam.
What is the difference between polystyrene and Styrofoam?
Polystyrene is a synthetic aromatic polymer made from the monomer styrene. Styrofoam is a trademarked brand of expanded polystyrene foam, used for thermal insulation and craft applications. In general, polystyrene refers to the polymer, while Styrofoam specifically refers to the foam product.
Does 1kg of lead take up more space then 1 kg of polystyrene?
No, 1 kg of lead will take up less space than 1 kg of polystyrene because lead is denser than polystyrene. Density is the amount of mass per unit volume, so lead, being denser, will occupy less volume compared to the same mass of polystyrene.
Can high density expanded polystyrene be used as wall of house?
Not AS the wall of a house but it can be used as part of the wall of a house (as insulation).
