Results: Show your work and include units. Wateh your signs. Enter the results of all calculations in the Results Table at the end of this section: 9. For each trial, calculate the heat energy change of the surnoundings (water) in joules when the cold pack solid dissolved in water. (Remember: q=mcT,m represents the mass of solution (water +NH4NO3 ). and assume that c (specific heat) is equal to 4.18J/(gC).) Trial 1: Trial 2
