Please Model 4Calorimetry involves the measurement of heat flow from one object (often the system) toanother (often the surroundings). The instrument chemists use to measure changes in heatenergy is called a calorimeter. The calorimeter is composed of an insulated container (like aStyrofoam cup) containing a measured mass of water. A thermometer rests in the water. Areaction vessel is also placed inside the water - this is where the reaction actually occurs. Thereaction vessel is surrounded by the measured mass of water. We will assume that thecalorimeter is a closed system where all the energy released by one object is absorbed by theother and vice versa.Tharmometerheat lost-heat gainedvesseWater LineReaction VesselCalorimeter If energy is absorbed by the reaction that is taking place, where will the heat be absorbed from?What will happen to the temperature of the surrounding water in the calorimeter?Does the amount of water present in a calorimeter affect the change in temperature?

In such calorimeter, amount of heat released in the reaction or used up in the reaction is…

If energy is absorbed by the reaction that is taking place, where will the heat be absorbed from? What will happen to the temperature of the surrounding water in the calorimeter? Does the amount of water present in a calorimeter affect the change in temperature? How? A neutralization reaction is a highly exothermic reaction. Would you expect the temperature of the water to increase or decrease? Explain in terms of system and surroundings. If you knew the temperature change in the water, its mass and its specific heat, what could you do with this information? How could you use this to find the amount of heat lost during the reaction? (Hint: think about whether the signs on loss and gain of heat are the same)
