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

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
