In a calorimetry experiment, 4.00 g of potassium iodide was added to 150 mL of water. If the temperature decreased by 8.70 C, the molar enthalpy of solution for potassium iodide is +/- kJ/mol. Give your 3-digit answer below rounded to the nearest whole number.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
