Answer:
Q = 1190 [cal]
Explanation:
In order to solve this problem, we must use the following equation of thermal energy.
[tex]Q=m*C_{p}*(T_{final}-T_{initial})[/tex]
where:
Q = heat energy [cal]
Cp = specific heat = 1 [cal/g*°C]
T_final = final temperature = 120 [°C]
T_initial = initial temperature = 50 [°C]
m = mass of the substance = 17 [g]
Now replacing:
[tex]Q=17*1*(120-50)\\Q=1190[cal][/tex]
