heat of combustion for naphthalene. This is the some basic bomb procedures. In this experiment‚ we us naphthalene as a fuel in bomb calorimeter which naphthalene powder is turned to pellet using pellet press. The fuel is burnt at constant volume condition in a high pressure container (the bomb). The whole bomb‚ pressurized with excess of oxygen. The mass of iron wire‚ ma =0.02g. The mass of naphthalene pellet with iron wire‚ mb =0.38g. The bomb is submerged in 850g of water and the initial temperature

The Stamp of One Defect “To know a man well were to know himself” (5.2.139)‚ the definition of a foil in Hamlet’s own words. In literature foils can be used to contrast and highlight specific qualities of the protagonist or other main characters. Hamlet has many foils throughout the play‚ which help to aid in the understanding of Hamlet’s character and his motivations. However‚ three characters in particular‚ Laertes‚ Horatio and the First Player play key roles in how Hamlet ultimately takes his

Hiroshima: Was Dropping the Atomic Bomb a Military Necessity? On the morning of August 6th‚ 1945 at around 8:16 a.m.‚ the United States dropped the first bomb on Hiroshima. This bomb was given the nickname “Little Boy.” Three days after the first atomic bomb was dropped‚ on August 9th‚ 1945 at around 11:02 a.m.‚ the United States dropped a second atomic bomb on Nagasaki. This bomb was given the nickname “Fat Man.” These two bombs immensely destroyed these cities and took the lives of many people

Harbor. Government funded atomic weaponry research had begun not long before the attack‚ and this has led people to believe that the Manhattan Project‚ a descendent of the program‚ was a knee-jerk reaction to the bombing. According to writer Brenda Wilmoth Lerner in her article on the Manhattan Project for the Encyclopedia of Espionage‚ Intelligence‚ and Security‚ Roosevelt ordered‚ in December of 1941‚ that research was to begin regarding the plausibility of building an atomic weapon‚ just following

September 2011 ISOTOPES Atoms of a given element which have the same number of protons but different numbers of neutrons are called isotopes. Thus‚ isotopes have the same position in the periodic table‚ the same chemical properties and the same atomic charge. The simplest example of an atom with different isotopes is hydrogen. The three isotopes of hydrogen are shown here: The increasing number of neutrons in the nucleus of the hydrogen atom adds mass to the atom and thus each isotope of a given

The Atomic Mass of Metallo You may have noticed on the periodic table that the atomic mass of an element is usually not a whole number. That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however‚ they are just a little different from every other atom of the same element. Most of the carbon atoms in the universe are Carbon-12‚ with 6 neutrons. A small percentage of carbon atoms are Carbon-13‚ with 7 neutrons

Atomic energy is energy produced by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility ofatomic energy.[1] The term was popularized by H. G. Wells in the phrase‚ "splitting the atom"‚ devised at a time prior to the discovery of the nucleus. Atomic energy also may refer to: * Nuclear binding energy‚ the energy required to split a nucleus of an atom * Nuclear potential energy‚ the potential energy of the particles inside an atomic nucleus * Nuclear

President Harry S. Truman‚ atomic bombs were dropped on Hiroshima‚ and Nagasaki‚ marking the only time nuclear weapons were used in warfare in all of U.S. history. It roughly killed about 129‚000-246‚000 or more people. Using a weapon of such untold destructive force‚ it made Japan finally announced its surrender to the Allies.

These defects can involve: The interior walls of the heart The valves inside the heart The arteries and veins that carry blood to the heart or the body Congenital heart defects change the normal flow of blood through the heart. There are many types of congenital heart defects. They range from simple defects with no symptoms to complex defects with severe‚ life-threatening symptoms. Congenital heart defects are the
