Answer:
Q = 246 kJ
Explanation:
It is given that,
Mass of water, m = 200 g
Let initial temperature, 
Final temperature of water, 
We know that the specific heat capacity of water, 
So, the heat energy needed to raise the temperature is given by :

or
Q = 246 kJ
So, the heat energy of 246 kJ is needed.
