PLEASE HELP A group of students designs a simple system that could be used to generate heat. The students use the compound
sodium acetate (NaC, H,O,) for the experiment. They dissolve a specific amount of NaC, H30, in 100 grams (9) of
water placed in an insulated cup. They measure the initial temperature of the water in degrees Celsius (°C) and the
maximum temperature reached by the mixture of water and NaC, H,O2. The diagram shows their experimental
setup.
