They also are brittle because once a force (hit) is applied to the compound, the ions with the same charges, lineup, repel, and split apart. Ionic compounds cannot conduct electricity as a solid because they don’t have mobile particles. Due to the fact it’s a solid, the particles are stuck together, shaking in place and don’t have the ability to move in one general direction. The ions are unable to come into contact with the electrodes of the probe. Ionic compounds are soluble in water. The H20…

Priest — Physicist — Philosopher A priest, a physicist, and a philosopher go into a bar … ostensibly, to consider principles of religion and science. One is an idealist. One is a materialist. One is a pragmatist. One is a religious scientist; but which one is which? — The physicist wonders how the universe works, but never asks why, because, to ask why is to become a metaphysician. — The philosopher thinks he knows why, but never asks how it works, for to ask how requires one to become a…

possible to obtain aggregates fineness modulus corresponds to the sum of percentages retained accumulated mass of an aggregate in the series of sieves Normal divided by 100. The particle size below is 80% which is of the total weight of the material. It is one of the parameters used to characterise it. In the D 80 were used the particle sizes below which lie 10%, 50% and 90% by mass, or is, D 10 , D 50 and D 90 , respectively. Another parameter was not the coefficient uniformity (CNU). The…

The beach has three major parts: beach face, berm and back beach. The area above the water, including the intertidal zone, is known as the beach berm. Beach berm can include vegetation, such as trees, shrubs, or grasses. The most familiar characteristic of a beach berm is its type of sand or rock (Marinebio.net, 2014). Along the backshore, accumulations of wind-blown sand may form sand dunes, and when these are sufficiently stable they become consolidated by a characteristic dune vegetation, for…

discoveries using the Web. Companies like the European Organization for Nuclear Research (CERN) publish their data regarding particle physics and also allow for other organizations to contribute to their databases and documentation. CERN even allows input from small particle detectors located in high schools throughout the nation, including my own high school. I was involved in our particle physics research team and I contributed to CERN’s data, learned from CERN’s…

main filter removes finer sized particles. In simple words, this great model can remove air impurities like no other and can help you breathe and sleep better.…

respectively. The relative effect of momentum diffusion to particles diffusion is presented by Schmidt number. For , the particles diffusivity dominates. Decreasing the particles diffusivity produces an increase in the temperature gradients and means an increase in Schmidt number. So, it is observed that Schmidt number enhances the temperature. Meanwhile, the higher values of Schmidt number correspond to a reduction in the particles diffusion. So, the concentration decreases with increasing…

Instrument: Respirable dust sampler Principle: Air is drawn through a size-selective inlet and through a 20.3 x 25.4 cm (8 x 10 in) filter at a flow rate which is typically 1132 L/min. Particles with aerodynamic diameter less than the cut point of the inlet are collected by the filter. The mass of these particles is determined by the difference in filter weights prior to and after sampling. The concentration of PM10 in the designated size range is calculated by dividing the weight gain of…

Community Acquired Pneumonia Pneumonia is an infection of the lung that involves alveoli, also known as air sacs, and is caused by various microbes including viruses, bacteria, or fungi. It is one of the leading causes of mortalities across the globe. Pneumonia commonly occurs in persons living in their home community hence the community-acquired pneumonia and also among patients who may be hospitalized for other dissimilar reasons as to pneumonia, hospital-acquire pneumonia. Up until 1930,…

from the sky. I have often wondered what causes such a terrifying occurrence, which is why I plan to explain the causes of lightening. Generally produced in thunderstorms, lightening is formed when liquid and ice particles above the freezing level collide. Once the liquid and ice particles collide, they build up large electrical fields in the clouds. A “spark” occurs whenever these electric fields become large enough to produce static electricity. The static electricity reduces the charge…
