[powerpoint]. As tritium is a radioactive particle, it breaks down over time and releases emissions as it does so. Tritium is a relatively weak radioactive particle and as it breaks down to helium, it releases weak beta emissions. [http://hps.org/documents/tritium_fact_sheet.pdf]. 2.
During this first of the atomic bomb scientist described as terrifying and outstanding. The explosion was as powerful as 15,000 -20,000 tons of TNT. The bomb was tested in a desert in New Mexico, where the surrounding sand in the area the explosion of it was made, turned into glass because of the extreme heat. The bomb was composed of uranium and plutonium, where they give and release a large amount of energy causing a lot of damage. The atomic bomb can make a lot of damage.
The resulting molten material is called the blister and contains about 99% copper by mass. (Cavette, 2007) Refining The copper blister is 99% copper but it still have a higher level of sulfure, oxygen some other impurities and by the reason it has to be further refined in order to purifies the cupper, this done by fist firing refined before it is sent to the final electro fining process • The blister copper is heated in in the refining furnace that is similar to the converter ,air is blown into the molten blister to oxides the impurities and a sodium carbonate is added to remove traces of arsenic and the antimony, • The blister copper is heated in a refining furnace, which is similar to a converter described above. Air is blown into the molten blister to oxidize some impurities. A sodium carbonate flux may be added to remove traces • Then the purified copper in then poured into the molds to form large electric
When α-Fe is heated above the critical temperature of 1420 °F, it causes the random thermal agitation of the atoms to exceed beyond the oriented magnetic moment of the unpaired electron spins happening in the 3d shell. It forms the low-temperature boundary of the beta iron field. β-Fe is crystallographically identical to α- Fe, with the exception of the magnetic domains and the expanded body-centered cubic lattice parameter which exists as a function of temperature, and is therefore not critical in steel heat treating. The beta phase is not regarded as a distinct phase and is only the high-temperature end of the alpha phase
Chemical properties Pyridine is miscible with water and virtually all organic solvents.  It is weakly basic, and with hydrochloric acid it forms a crystalline hydrochloride salt that melts at 145–147 °C.  Most chemical properties of pyridine are typical of aheteroaromatic compound Molecular properties Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. In contrast to benzene, the electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom.
The blast wave resulting from the explosion caused windows within 10 miles to shatter and was felt up to 37 miles away from ground zero. The thermal pulse from the explosion ignited numerous fires in the city, incinerating all the buildings within 4.4 miles of ground zero. 30 minutes after the bomb exploded, a “black rain” containing highly radioactive particles that were sucked up into the air at the time of the explosion and during the fire started falling in areas northwest of Hiroshima, contaminating surrounding areas with radioactive particles. On August 9, 1945, at 11:02 a.m., the atomic bomb “Fat Man” was detonated above the city of Nagasaki. An implosion-type device with a core of
The waste produced by the power plant has the ability to seek into the main water supply and the soil, evidently making the sources radioactive. Threats have also presented itself of possible attacks on a nuclear power plant. The dangerous and lethal effects that if a nuclear power plant were to have a meltdown are extreme. The radioactive material has the ability to travel and expand further than a uranium nuclear blast. The death toll will increase as radiation will travel for miles and miles reaching places that are not in near of the power plant.
English scientist Sir William Crookes discovered thallium in 1861. Atomic number for thallium 81g, atomic weight 204.383g . him The melting temperature of 303.5 °C, while boils at a temperature of 1457 ° C. And its density is 11.85 g / cm² at 20 ° C class The metal thallium is highly toxic to humans. As the feature is a cumulative effect, it increases with the passage of time. And exposure to a lot of this element may cause some diseases and suspected thallium potential carcinogenic to humans.
White adipocytes are globular in shape and the size of the lipid droplet stored in them determines how big they get. This lipid droplet comprises of triglyceride which takes up more than 90% of the cell volume. Mitochondria in white adipocytes are thin, elongated and variable in amount. On the contrary, Brown adipocytes contain many small lipid droplets as well as a high number of mitochondria. Brown adipose gets its dark red-brown colour from its high iron content found in the mitochondria.
Candle wax has the following states: • Melting point = 470C -650C • Boiling point = 1880C • Flash point = 1980C (where candle wax starts to burn) 3.6.2 What happens to the air inside the jar? Now that you have a fire, warm gases start to be produced. When the hydrocarbon starts to breakdown/up it breaks up into hydrogen and carbon. The hydrogen mixes with the oxygen (O2) to form water vapour (H2O) and carbon to form carbon dioxide (CO2). The water vapour condenses on the cold surface of the jar to form water.
Or sometimes a molecular cloud. They both contain many different types of atoms. For examples metals and gasses. The clouds are huge in size. The average temperature of an interstellar cloud are about 10 K. The density is about 1 Billion particles.
The physical properties of Barium are solid, pale yellow, shiny, and a malleable metal in room tempature. The melting point and boiling give off a pale-green yellow. Some very interseting chemical properties of Barium is that it is malleable, flammable, very active, Alkaline Earth Metal Group, can be toxic, can react to water and other acids, but finally, to prevent such reacting, Barium is stored under Kerosense, Petrolem, or some other oily
The waste contains poisonous elements such as plutonium. Low level waste is when the item used as fuel is contaminated or becomes radioactive. Also when material would be exposed to neutron radiation. High Level waste is the byproduct left inside the reactor after the nuclear reactions occur. This byproduct is more radioactive and takes longer to dispose of.
The air on Venus is mostly carbon dixide,this is because of its thick atmosphere Traps the air in planet in. (https://www.nasa.gov/content/goddard/nasa-research-helps-unravel-mysteries-of-the-venusian-atmosphere) Since Venus has a thick Atmosphere The pressure there will crush any lender that tries to Well land. Earth has a strong magnetic field that protects its Venus however does not have That type of protect.The first mission to Venus started over 25 years ago.Venus is 67 million miles away from the
Finally, there is pulverized dust on the surface of Mercury. This likely also comes from the collisions that have left the boulders and dents in the grey surface. Essentially, Mercury resembles our Moon in the looks department. Venus 's atmosphere is a very heavy one. It 's mostly made up of carbon dioxide (96.5%) and nitrogen (3.5%), however there are also varying small amounts of other elements, including carbon monoxide, helium, neon,
