energy density comparisons

. Different particles attain the state of momentary rest at different instants, The particles at the nodes are permanently at rest but other particles attain their position of momentary rest simultaneously. All the particles attain the same maximum velocity when they pass through their mean positio..

In order to determine the density of a substance or an object, we find out the mass and volume of the substance and use the relati..

Property carbon monoxide (CO) carbon dioxide(CO 2 ) Vapour density Almost as dense as air: Vapour density = 14: (Vapour density of air 14.4) 1.5 times as dense as air; Vapour density = 22 Solubility Almost insoluble in wate..

Single, double and triple covalent bonds differ from each other in the following ways. Single bond is formed by the sharing of one electron pair, (two electrons); a double bond is formed by the sharing of two electron pairs, (four electrons), whereas a triple bond involves sharing of three electron..

In metals, the conduction band and valence band partly overlap each other and there is no forbidden energy gap. In insulators, the conduction band is empty and valence band is completely filled and forbidden gap is quite large = 6 eV. No electron from valence band can cross over to c..

Sound waves can undergo reflection, refraction, interference and diffraction. But they cannot undergo polarization. Reflection of sound is evident in the environment in the form of echoes. The rolling of thunder is largely due to successive reflections from the clouds and land surfaces. For appre..

Question: How can you prove that air is a mixture? Answer: a) The composition of air is variable. The composition varies from place to place and with altitude. For instance, at higher altitudes, there is less oxygen in the air. In industrial areas, due to the waste gases coming out of in..

The orbital angular momentum of a 's' orbital is zero, as 'l' = 0. This means that the probability of finding an electron at a particular distance from the nucleus is the same in all directions/at all angles. Since the distribution of electron density is symmetrical, the shape representi..

>As a result of tetrahedral arrangement of H 2 O molecules in the solid state, the ice structure extends in three dimensions. Further the molecules of H 2 O are not packed closely as hydrogen bonds between oxygen and H atoms are longer than covalent bonds between them. This results in vacant spaces..

An atomic orbital is the space around the nucleus in which the probability of finding the electron is maximum. These most probable regions can be diagrammatically represented by cloud density (dot) diagrams. The density of dots (or lack of them) in any region of the cloud diagra..
