The energy required is given by mass*specific heat capacity*temperature rise

 

 

The specific heat capacity of water (in this temperature range) is 4184 J/(kg.degC)

 

To answer your question you need to specify the starting temperature of the water as well, as it is the temperature difference that matters.
