The amount of energy needed to boil away the water at the initial temperature is 301,248 J.
Energy required to boil the water
The amount of energy needed to boil the water at the given is calculated as follows;
Q = mcΔθ
where;
density of water = 1000 g/L
mass = density x volume
mass of water = 1000 g/L x 1.6 L = 1,600 g
Q = 1600 g x 4.184 J/g⁰C x (100⁰C - 55 ⁰C)
Q = 301,248 J
