How can you lower the materials density?
Oil floats on water, and has a lower density.
Iridium wins when the density is calculated using the "space lattice" method, which is considered to be more accurate, when comparing it to Osmium. An atom of Iridium has 77 p…rotons, 77 electrons and 115 neutrons. At.wt. 192.22 An atom of Osmium has 76 protons, 76 elections and 114 neutrons. At. wt. 190.2 Osmium has a crystal structure that is "Hexagonal" Iridium is a "Cubic face centred" crystal. This crystal structure is how the atoms align with each other to form the material itself. A good example to understand this is with Carbon. A very dense and very hard form is DIAMOND where the carbon atoms are very tightly and closely bonded together. A very soft form is GRAPHITE, where the carbons atoms are very loosely packed and easily parted from each other. The Iridium structure's "space lattice" is more compact than that of Osmium such that more protons, neutrons and electrons fit into a unit volume and thus it is denser.
What is the angle of incidence when a beam of light passes at an oblique angle into a material of lower optical density?
The angle of incidence is the angle of the beam of light and the plane surface of the object, usually measured in degrees When a beam of light passes at an oblique… angle into a material of lower optical density, the angel of incidence is less than the angle of refraction. Light bends towards the dense medium and bends away from the less dense medium.
When a beam of light passes at an oblique angle into a material of lower density the angle of incidence is?
less than the angle of refraction.
the density of the lower mantle is 3.4-4.3g/cm
Solids tend to have a higher density because the molecules are arranged closer together where as in gases the molecules are further apart. Since density is Mass/Volume, and so…lids have more mass per volume than gases it is more dense
The young modulus of a material is a constant. It CANNOT be changed. The young modulus E of a material is given by: E = Fl/Ae where F is the force acting on the material l is …the length A is the cross-sectional area and e is the extension of the material This formula applies ONLY when the proportionality limit is not exceeded. One might expect that changing either one of F, l, A or e will change E. In fact, what happens is that another quantity changes so as to keep young modulus constant. For example, when the force F is increased, the extension e increases by the same factor (Hooke's law) such that E remains constant. You will see that whatever quantity(ies) you wish to change, the Young modulus of the material will remain constant.
The liquid on top will have the highest density because it doesn't contain so much weight and the liquid on bottom will hold more density because it contains more weight…. I don't really know though. I think its right. (: good luckkk
Since the material is being heated, the particles in the material begin to move. this takes up more space, making the material less dense.
density is a reflection of a couple of things. 1) how heavy the atoms are (where on the periodic table) 2) how closely packed they are (what is their intermolecular intera…ction/ lattic structure)
atoms in a gas are farther apart than atoms in a liquid
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel… hull and the air inside the hull.
When a beam of light passes at an oblique angle into a material of lower optical density what is the angle of incidence is?
less than the angle of reflection
density is mass/volume that is the total mass per 1cm3 of the liquid in question. as water becomes colder, its particles loose energy and move closer together, increasing the …number of particles per 1cm3 and therefore increasing the amount of mass in that 1cm3
Usually, when something turns into solid, its volume reduces. Since density is given by mass per unit volume, decrease in volume means higher densities. Water, however has an …anomaly, on freezing, its volume, instead of contracting, actually expands. As the mass of the particular quantity under observation remains constant, increase in volume on freezing cause the density to go down, below water in the liquid form. Thus, the density of ice is lower that that of water.
