Answer:
Final temperature is 83.236 °C.
Explanation:
Let final temperature to be 'T'
There is a theorem :
ΔQ = m·s·ΔT
ΔQ : Heat exchange = -1300 J (<em>it is negative because heat is released</em>)
m : mass which exchanges heat = 40 grams
s : specific heat capacity of water = 4.186 J/grams °C = 1 Calories/grams °C
ΔT : Change in temperature = T - 91°
-1300 = 40 × 4.186 × (T-91)
