A well insulated calorimeter contains 100 ml of water. 0.100 mal of solid potassium nitrate is added to the water and stirred unel it has all dissolved. The water was initially at a temperature of 18.00 °C. After all the potassium nitrate has dissolved the temperature is 7.90 °C. The temperature change is caused by heat energy a. lost from the calorimeter and water to the surroundings b. absorbed from the surroundings into the calorimeter and water c. due to the reaction of potassium nitrate with water od absorbed in the solution process Clear my choice
