A 25 g cube of metal was heated in a hot temperature bath to 80oC and then added to 50 mL of deionized water. Using the following graph, explain how you would determine the temperature change that has occurred in the system. The metal was added to the calorimeter (Styrofoam cup with water) at 180 seconds. What is the initial temperature of the water and the metal? What is the final temperature of the metal and the water? What occurred...

If a block of metal is placed in a calorimeter and the water in the calorimeter gets warmer, determine the direction that heat flowed by defining the system and surroundings. Was heat lost or gained by the system? If +3220 J of heat is lost to the water in a calorimeter by an exothermic reaction at constant pressure, what is the enthalpy of the reaction? In two sentences or less, define the term standard heat capacity as it applies to...
