Answer:
80°C
Step-by-step explanation:
The change in temperature can be calculated my using the specific heat capacity equation as follows;
Q = m × c × ∆T
Where;
Q = amount of energy (J)
m = mass (kg)
c = specific heat capacity of water (J/kg°C)
∆T = change in temperature (°C)
According to this question, Q = 201,600J, m = 600g = 600/1000 = 0.6kg, c of water = 4200J/kg°C
Using Q = m × c × ∆T
201600 = 0.6 × 4200 × ∆T
201600 = 2520 × ∆T
∆T = 201600 ÷ 2520
∆T = 80
Change in temperature (difference in initial and final temperature) is therefore 80°C
