Experiment B2‚ Heats of Combustion – The Bomb Calorimeter. Objectives: To calibrate a bomb calorimeter by the combustion of benzoic acid. Then to use the calibrated calorimeter to measure the heat of combustion of naphthalene and calculate the heat of formation of naphthalene. Theory: q = C.ΔTBA C = q / ΔTBA Moles = mass / Mr ΔŪ = ΔU / moles ΔHoc‚298 = ΔŪoc‚298 + PDV = ΔŪoc‚298 + RTΔn C10H8 (s) + 12O2 (g) 10CO2 (g) + 4H2O (l) ΔHoc‚298 = - 1

Why did the Truman Administration decide to drop the atomic bombs on Japan in 1945? There has been much debate as to why Truman elected to drop the atomic weapons on Hiroshima and Nagasaki in the summer of 1945. Historians have long debated the true purpose to which the atomic bombs were designed to fulfil upon there deployment. The Alperovitz thesis of the 1960 was accepted for many years. The thesis revolved around the idea that the atomic weapons were deployed as diplomatic tools to intimidate

1. Environmental impacts of nuclear waste. Nuclear waste or radioactive waste is the residue of nuclear reactors‚ nuclear researches‚ nuclear projects and nuclear bomb reaction. Nuclear wastes‚ also known as spent fuel‚ are dangerously radioactive and could exist for thousands of years. The release of nuclear waste from its reactor could easily cause a lot of diseases like acute radiation sickness. The injection of nuclear waste to underground water causes water pollution and could contribute

atomic bomb. First‚ he shouldn’t have dropped “Little Boy” in Nagasaki because “The explosion in Nagasaki immediately wiped out 90% of the city and it killed over 80‚000 people”. That is an incredibly large amount of population. If you think about it‚ that’s very sad and no one should suffer the attack from a nuclear bomb. Secondly the bomb was illegal to use (yes I said ILLEGAL). “On September 30th‚ 1938 the League Of Nations issued an unanimous resolution outlawing the intentional bomb of civilian

Ehrlich’s Population Bomb "People are realizing that we cannot forever continue to multiply and subdue the earth without losing our standard of life and the natural beauty that must be part of it. these are the years of decision- the decision of men to stay the flood of man." Ehrlich here explains the one of the most pressing problems facing man in the 20th century. In Population Bomb‚ Ehrlich explains that pollution‚ shortages‚ and an overall deterioation of the standard of living is all due

The Atomic Bomb The atomic bomb is a powerful‚ explosive nuclear weapon. It is fueled by the fission of the nuclei of specific amounts of plutonium or uranium‚ in a chain reaction. The strength of the explosion created by one of these bombs is equal to the strength of an explosion created by thousands of tons of TNT. The atomic bomb was first created in the early twentieth century. Physicists in the United States and Europe had discovered that the fission of uranium could be used to create

ALBERT EINSTEIN and the ATOMIC BOMB The physicist Albert Einstein did not directly participate in the invention of the atomic bomb. But as we shall see‚ he was instrumental in facilitating its development. In 1905‚ as part of his Special Theory of Relativity‚ he made the intriguing point that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate this

the war. Disadvantages – Truman made an atomic bomb to kill in large amounts. 1. Truman invaded Japan and dropped an atomic bomb on the Japanese city. 2. The firing bomb attack killed more than 80‚000 people in Tokyo. Option #2 – Japans ground invasion. Advantages – The Japanese did not surrender that easy. 1. If the United States invaded Japan homeland they would have fought even more aggressively. 2. Truman was terrified that the Japan invasion would look like Okinawa. Disadvantages – Truman and

Debate Intro The pictures in front of you are the gruesome results of the utter destruction after the atomic bombs were dropped on both Japanese cities. Almost half a million victims; equivalent to 13‚000 tons of TNT; a 1.6 mile radius of destruction/bomb (within that radius‚ people were disintegrated‚ leaving shadows where they stood). Housewives and children were incinerated instantly‚ their internal organs boiled and their bones charred into brittle charcoal. 65% of the casualties were nine

One of the most interesting phenomena in Nuclear Physics with far reaching consequences is nuclear fission. Nuclear fission is defined as the splitting of heavy nuclei to release energy. This aspect holds many opportunities and possibilities for our technologically advancing world. Fission Process (Theory) In the case of large atoms‚ such as Uranium‚ the impact of a particle on the nucleus loosens its binding force. The impact causes the nucleus to break apart into pieces‚ also known as fission
