    Heat of Neutralization Lab   Objective:​  The objective of this lab was to measure‚ using a calorimeter‚ the energy changes  accompanying neutralization reactions.    Background:​  Chemical changes are always accompanied by a change in energy‚ typically as  heat. If the reaction releases heat  (ΔH  <  0) then the reaction is exothermic. If the reaction  absorbs heat  (ΔH  >  0) then the reaction is endothermic. The quantity of heat is measured  experimentally by having the reaction take place in an insulated container called a

    Specific Heat Lab Objective: Find the specific heat of the unknown metal given using calorimetry. Background Theory: In every reaction‚ energy is transferred between a system and its environment. A system encompasses the substances that are involved in a reaction‚ and everything else in the universe other than the system is called the environment. The standard SI unit of energy is Joules (J). Temperature is the level of excitement of the atoms in a substance. In most cases‚ energy is

    Ten Minutes of Specific Heat Remi Adams East Rowan High School AP Environmental Science Abstract Specific heat and climate were the primary focus of this lab. Specific heat is defined as “the measure of the ability of a substance to change temperature”. The purpose for carrying out this lab was to determine the specific heat/rates of both soil and water‚ and then comparing them. Students also were to relate specific heat to climate. Students were to determine which substance expressed

    Discussion Based on the results of the lab it can be seen that the metal in the lab can be identified as lead. The identity of the metal was determined by the heat energy calculations. The heat capacity that was found matched closely to that of the lead. There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the

    In this lab‚ we will measure the heat of combustion‚ or calorimetry‚ of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab‚ we must first determine the mass of the tea candle. Then‚ we will determine our room temperature‚ measure about 100 mL of chilled water‚ and then pour the water into the given empty

    8/2/15 Lab Report Experiment to measure the latent heat of vaporisation of water Theory Latent heat of vaporisation is when a liquid is heated enough to start boiling‚ at this point‚ even if the source of heat keeps heating the liquid‚ the liquid’s temperature will not rise any further until all of the liquid is converted to gas. For example‚ if water is boiling in a kettle‚ and the kettle is left on whist the water is boiling‚ the water’s temperature will not exceed 100°C because all the heat energy
