The students conducted a calorimeter experiment and placed NaOH into the water. The initial
temperature of the water is 46.5°C. Use the picture for the final temperature data. How did the heat
transfer between the surrounding water and the system (NaOH) within the calorimeter?
a. the surrounding (water) lost heat, the system (NaOH) gained heat
Coffee Cup Calorimeter
b. the surrounding (water) gained heat, the system (NaOH) lost heat
Final Temperature61.0°C
c. the surrounding (water) and the system (NaOH) lost heat
d. the surrounding (water) and the system (NaOH) gained heat
