An exothermic reaction is conducted in an insulated calorimeter filled with water. The calorimeter is then sealed so that there is no heat exchange between the contents of the container and the surrounding air. Which of the following statements is true about the reaction?

The thermometer in the water bill show a decrease in temperature.

The potential energy of the products will be higher than that of the reactants.

The water increases in temperature as the reaction gets off energy.

The total energy of the reaction will increase.

so you have a cup of water with a smaller container within it, where an exothermic ("heat-releasing" reaction is occurring).

Heat transfer of the thermal energy will occur from the reaction occurring in this smaller container to the water in the larger cup increasing it's temperature.|dw:1444004747467:dw|
