Chemistry

? value of diffusion depends on mass(molecular mass low, rate high) + temporaryorary worker( temp low, rate low) ?solid : particle argon packed virtually to prevailher in an orderly manner; wad notwithstanding flutter and rotate abt their fixed position; unfluctuating forces amid the particles; low susceptibility content as pop offment is restricted ? fluent: particles ar packed closely together plainly not in an orderly arrangement; can vibrate,rotate and move passim the liquid, they clash against each otherwise, are held together by strong forces but weaker than the forces in a solid, higher energy content. ? bodge: particles are very(prenominal) far apart from each other and are in a random arrangement; can vibrates, rotate and move freely, the rate of collision is greater than the rate of collision in a liquid; weak forces amidst particle, highest energy content as movement is random. Sublimation: iodine, ammonium chloride, NH4CL, alter ice(solid CO2) ?Heat ing of dealhthalene(mp:80) : during the melting process, the temp remains constant because the rut energy absorbed by the particles is used to overcome the forces amidst particles so that the solid can playing period into a liquid.

At this temp, both solid and liquid are present water clean is used to ensure eternal rest heted evenly+nap is flammable ? cool down of naphthalene: during the frost process, temp remain constant becoz the heat expiry to the surroundings is exactly balances by the heat energy liberate as the particles attract one another to form a solid. nap is stirred continuously to avoid supercooling( temp drops at a lower place ! freezing point, without appearance of solid) ?Daltons : ball, Thompson: negatron, Rutherford: proton+nucleus, Bohr:electron move in shells, Chadwick: neutrons ?Isotope: same num of proton, but diff num of neutron, diff physical property(density, mp, bp) cobalt-60: beam of light for cancer,plutonium-238: regulate the heartbeat,iodine-131: thyroid disease,uranium-235: nuclear power, phosphorus-32: uptake of phosphate+ metamorphosis of phosphorus, carbon-14:...If you want to get a full essay, order it on our website: OrderCustomPaper.com
