thought that electricity was of animal origin and could be found only in living tissues. A few years later‚ in 1800 Alessandro Volta discovered that electricity could be produced through inorganic means. In fact‚ by using small sheets of copper and zinc and cloth spacers soaked in an acid solution‚ he built a battery - the first apparatus capable of producing electricity. Naysayers were quick to predict that electricity would never serve a useful purpose. Obviously they were very wrong. Electricity

Experiment 3: Enthalpy of Various Reactions Introduction A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus‚ which is made from two styrofoam cups with plastic lids and a thermometer‚ to measure changes in thermal energy of various reactions. When using this type of apparatus‚ it is assumed that no heat is transferred between the calorimeter and the surroundings‚ and that
