    calorimeter was standardized using benzoic acid and the average heat capacity of the bomb calorimeter was calculated to be 10.60.3205 kJ/K. From that‚ the These results show that heats of combustions of unknown substances can be determined via bomb calorimetry. Introduction The first law of thermodynamics states that energy is conserved.2 Using that law it can be said that the change in the internal energy of a system () depends on the heat added (q) to the system and the work (w) done by the system

    409 Lab 40: Calorimetry Calorimetry is the measurement of the quantity of heat exchanged during chemical reactions or physical changes. For example‚ if the energy from an exothermic chemical reaction is absorbed in a container of water‚ the change in temperature of the water provides a measure of the amount of heat added. Calorimetry involves the use of a calorimeter. In this activity you will learn how the energy change in a physical change can be measured using a calorimeter. •

    most environmentally friendly way of drinking from a cup or mug? Reusable cups are usually the preferred method as long as the cups get used a lot. As for disposable cups‚ the main three choices are paper‚ styrofoam‚ and plastic. Plastic cups are the cheapest to purchase but they can’t be used for hot drinks. Pricewise‚ plastic cups cost $11 for 1000. Styrofoam costs $25 for 1000. Paper cups cost $80-120 for 1000. 100% compostable paper cups costs around $100 for 1000 made from natural corn starch

    Calorimetry: Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding
